Book excerpt: Neutron-rich rare-earth nuclei were produced in multinucleon transfer reactions of 17°Er and 176Yb projectiles on {sup nat}W targets at the Lawrence Berkeley Laboratory SuperHILAC and their radioactive decays properties studied at the on-line mass separation facility OASIS. Two unknown isotopes, 169Dy (t 12 = 39 {plus minus} 8 s) and 174Er(t12 = 3.3 {plus minus} 0.2 m) were discovered and their decay characteristics determined. The decay schemes for two previously identified isotopes, 168Dy (t12 = 8.8 {plus minus} 0.3 m) and 171Ho (t12 = 55 {plus minus} 3 s), were characterized. Evidence for a new isomer of 3.0 m 168Ho{sup g}, 168Ho{sup m} (t12 = 132 {plus minus} 4 s) which decays by isomeric transition (IT) is presented. Beta particle endpoint energies were determined for the decay of 168Ho{sup g}, 169Dy, 171Ho, and 174Er, the resulting Q[beta]-values are: 2.93 {plus minus} 0.03, 3.2 {plus minus} 0.3, 3.2 {plus minus} 0.6, and 1.8 {plus minus} 0.2 MeV, respectively. These values were compared with values calculated using recent atomic mass formulae. Comparisons of various target/ion source geometries used in the OASIS mass separator facility for these multinucleon transfer reactions were performed. 73 refs., 40 figs., 11 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: The isotope separator facility OASIS, on-line at the Lawrence Berkeley Laboratory SuperHILAC, was used to investigate proton-rich rare earth nuclei. Single-particle states near the 82-neutron shell were delineated, numerous new isotopes, isomers, and [beta]-delayed proton emitters were discovered and the [alpha]-decay properties of some nuclides with N> 84 were reexamined. In this contribution the experimental program is summarized briefly, the excitation energies of the s12 and h112 proton states in this mass region are discussed, and results on the [beta]-delayed-proton spectra of 145Dy and 147Er are presented. 17 refs., 5 figs.

Available in PDF, EPUB and Kindle. Book excerpt: The understanding of thc details of nucleosynthesis in stars remains a great challenge. Though the basic mechanisms governing the processes have been known since the pioneering work of Burbidge, Burbidge, Fowler and Hoyle (l), we are now evolving into a condition where we can ask more specific questions. Of particular interest are the dynamics of the s ('slow') process. In this process the general condition is one in which sequential neutron captures occur at time scales long compared with the beta decay half lives of the capturing nuclides. The nucleosynthesis period for C or Ne burning stellar shells is believed to be in the year to few year time frame (2). This means that radionuclides with similar half lives to this burning period serve as 'branch point' nuclides. That is, there will be a competition between a capture to the next heavier isotope and a beta decay to the element of nexl higher atomic number. By understanding the abundances of these competing reactions we can learn about the dynamics of the nucleosynthesis process in the stellar medium. Crucial to this understanding is that we have a knowledge of the underlying neutron reaction cross sections on these unstable nuclides in the relevant stellar energy regions (neutrons of 0.1-100 KeV). Tm (1.9 years) and ls'Sm (90 ycws) have decay properties that permit their handling in an open fume hood. These Iwo were therefore selected to be the first radionuclides for neutron capture study in what will be an ongoing effort.
