Available in PDF, EPUB and Kindle. Book excerpt: The high energy and high intensity of the continuous energy (white) neutron source at the WNR target area of the Los alamos Meson Physics Facility (LAMPF) may make possible a direct measurement of the neutron-proton bremsstrahlung (NPB) cross section. Several recent papers have discussed the operation of the WNR white neutron source in detail so we will just include a short description of the relevant properties of the source in this article. Next we will describe one possible method of measuring the NPB cross section which is based on two calorimetric detectors that measure the energies of the scattered neutrons and the recoil protons. There are several advantages in using a white neutron source for this type of measurement. First, a wide range of incident neutron energies may be covered. In the case of the WNR, the energy range is from below 50 MeV to over 400 MeV which is above the pion production threshold. Second, all incident neutron energies are measured simultaneously. The greatly reduces the systematic errors associated with sequential measurements at different beam energies when measuring the energy dependence of the NPB cross section. Third, the neutron beam is shared amongst several experimenters at WNR. This greatly reduces the competition for beam time, so longer runs are often possible compared to facilities that require the dedicated use of the accelerator. In the past, typical experiments have run for several months. 6 refs., 5 figs.

Available in PDF, EPUB and Kindle. Book excerpt: Nucleon-nucleon bremsstrahlung is a few-body radiative process that provides insight into several areas of nuclear physics. It is one of the simplest systems for studying the off-shell behavior of the nucleon-nucleon potential. The physics involved in neutron-proton bremsstrahlung (NPB) is significantly different from that of proton-proton bremsstrahlung (PPB). In particular, NPB cross sections are much larger than PPB cross sections because NPB allows E1 radiation, and the contribution to the cross section from the meson exchange currents has been calculated to be as large as the contributions from external radiation. To date there have been essentially four NPB experiments. These measurements have covered only a small part of the available phase space. A major experimental problem in performing these measurements has been the lack of a suitable intense, high-energy neutron beam. We are planning a measurement of the NPB cross section using the white neutron source at the WNR target area at the LAMPF accelerator. We plant to implement the experiment in three phases. In this first state, we shall measure inclusive hard-photon production using a multi-element gamma-ray telescope that is insensitive to neutrons. In the second phase, we shall measure the bremsstrahlung gamma-rays in coincidence with recoil protons. In the last phase, we shall detect the scattered neutrons in coincidence with the recoil protons and gamma rays. 8 refs., 6 figs.

Book excerpt: The triply-differential cross section for neutron-proton bremsstrahlung (np -+ np[gamma]) was measured at the WNR facility of Los Alamos National Laboratory. A liquid hydrogen target was exposed to the pulsed neutron beam, and the scattered neutrons and recoil protons were observed in coincidence at angles of 20°, 28°, and 36° on opposite sides of the beam. Measuring the proton and neutron energies allows the reconstruction of the full kinematics for each event. Events with incident neutron energies between 175 and 275 MeV are included in the data analysis so as to remain below the pion production threshold. The resulting photon angular distributions for each of the nine angle pairs are presented, and are compared with theoretical predictions.

This book was released on 2012-12-06 with total page 1041 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the Proceedings of the International Conference on Nuclear Data for Science and Technology held at Jillich in May 1991. The conference was in a series of application oriented nuclear data conferences organized in the past under the auspices of the Nuclear Energy Agency-Nuclear Data Committee (NEANDC) and with the support of the Nuclear Energy Agency-Committee on Reactor Physics (NEACRP). It was the fIrst international conference on nuclear data held in Germany, with the scientific responsibility entrusted to the Institute of Nuclear Chemistry of the Research Centre Jillich. The scientific programme was established by the International Programme Committee in consultation with the International Advisers, and the NEA and IAEA cooperated in the organization. A total of 328 persons from 37 countries and fIve international organizations participated. The scope of these Proceedings extends to a wide range of interdisciplinary topics dealing with measu rement, calculation, evaluation and application of nuclear data, with a major emphasis on numerical data. Both energy and non-energy related applications are considered and due attention is given to some fundamental aspects relevant to the understanding of nuclear data.
