Available in PDF, EPUB and Kindle. Book excerpt: The shell structure of nuclei far from stability evolves from the standard shell model picture that accurately describes stable nuclei. Experimental evidence has been given by changes in structural properties of nuclei such as the shell closures. The evolution of shell structure is gradual and must be studied by looking systematically at isotopic or isotonic nuclear chains. Studies of these chains can deepen the understanding of shell structures, magic numbers and the collective natures of nuclei far from stability.The neutron rich silicon isotopes display evidence of shell evolution seen in the ratio of the low-lying excitation energies. 34Si has a closed shell nature with a proton bubble structure which evolves along the isotopic chain to the absence of the N=28 shell closure expected in 42Si. Another complementary way to probe these changes is by studying the reduced transition rates of the first 2+ and 4+ states. The ratio of the reduced transition rates has characteristic values for different collective modes. However, these values are not known for isotopes that are more neutron rich than 30Si. The reduced transition rates can be compared to various theoretical models to understand the changes taking place in this neutron-rich region.This work discusses an experiment that studied 36Si and 38Si to determine the lifetimes of their excited states and to determine the reduced transition rates of the first 2+ and 4+ states in both nuclei. From these B(E2) values, the ratio is calculated and compared to the collective models and shell model calculations. The recoil distance measurement was conducted at the National Superconducting Cyclotron Laboratory using the S800 Spectrograph, the GRETINA array, and the TRIPLEX plunger. The experiment successfully measured the lifetimes of the 2+1 and 4+1 states in 38Si and the 4+1 and 6+1 states in 36Si. Results from the measurement included the confirmation of the 2383-keV state in 38Si that had only been seen once before. The B(E2) values determined from the experiment indicate the reduced collectivity for the first 4+ states of 36,38Si indicating the persistence of the N=20 magic number through 36Si and 38Si.

Available in PDF, EPUB and Kindle. Book excerpt: Lifetimes of the rotational levels in neutron-rich even-even Nd isotopes were deduced from the analysis of the Doppler broadened line shapes. The experiment was performed at Daresbury with the Eurogam array, which at that time consisted of 45 Compton-suppressed Ge detectors and 5 Low-Energy Photon Spectrometers. The source was in the form of a 7-mm pellet which was prepared by mixing 5-mg; 248Cm and 65-mg KCl and pressing it under high pressure. Events for which three or more detectors fired were used to construct a cubic data array whose axes represented the [gamma]-ray energies and the contents of each channel the number of events with that particular combination of [gamma]-ray energies. From this cubic array, one-dimensional spectra were generated by placing gates on peaks on the other two axes. Gamma-ray spectra of even-even Nd isotopes were obtained by gating on the transitions in the complimentary Kr fragments. The gamma peaks de-exciting states with I ≥ 12 h were found to be broader than the instrumental line width due to the Doppler effect. The line shapes of they-ray peaks were fitted separately with a simple model for the feeding of the states and assuming a rotational band with constant intrinsic quadruple moment and these are shown in Fig. I-27. The quadrupole moments thus determined were found to be in good agreement with the quadrupole moments measured previously for lower spin states. Because of the success of this technique for the Nd isotopes, we intend to apply this technique to the new larger data set collected with the Eurogam II array. The results of this study were published.

This book was released on 1993 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project was directed toward the study of neutron-rich nuclei using the experimental facilities at LAMPF, which is a part of LANL. The principal results of the investigation include the discovery of many new isotopes along with a measurement of their masses and in particular those nuclides in the Z = 7--19 and 14 --26 regions of the chart of the nuclides. Thirty-four new nuclides were detected and studied with their masses being measured with relatively high accuracy, and an additional twenty-six that were previously known and measured were remeasured to an improved accuracy. Besides providing new information about the mass surface in new and extended redons of the chart of the nuclides, this investigation enabled properties and previously unknown structure of some of the nuclei to be determined such as nuclear deformation among some of the nuclides. Also a study of the neutron pairing gaps and the proton pairing gaps among these nuclides was made. Other developments also achieved included instrument (TOFI) improvements and upgrades and theoretical investigations into the masses of the hadrons.

Available in PDF, EPUB and Kindle. Book excerpt: The neutron excess of the triton makes its possible to use this projectile in transfer reactions to reach nuclei of greater neutron excess than the target nucleus. Principal examples of such reactions are the (t, .cap alpha.), (t, p) and (t, 3He) reactions, all of which have been used to study neutron rich nuclei. The present report discusses several of these examples and reports on more definitive mass measurements and spectrosopy of the low lying levels of some of these nuclei. In particular, results of using a polarized triton beam are discussed as this study leads to many new spin assignments.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An extension of the atomic mass surface in the region A ≈ 100 is performed via massmeasurements of the 100-102Sr and 100-102Rb isotopes with the ion-trap mass spectrometer ISOLTRAPat CERN-ISOLDE. The first direct mass measurements of 102Sr and 101;102Rb are reported here. Thesemeasurements confirm the continuation of the region of nuclear deformation with the increase of neutronnumber, at least as far as N = 65.In order to interpret the deformation in the strontium isotopic chain and to determine whether an onsetof deformation is present in heavier krypton isotopes, a comparison is made between experimentalvalues and theoretical calculations available in the literature. To complete this comparison, Hartree-Fock-Bogoliubov calculations for even and odd isotopes are also presented, illustrating the competitionof nuclear shapes in the region.The development of an electrospray ionization ion source is presented. This source can delivera large range of isobaric masses for calibration purposes. The early commissioning of the sourceis discussed, including the results from the first mass scans detected behind the quadrupole massspectrometer. A resolution of a few atomic mass units is reached.
