Abstract

New measured differential cross sections of tritons and alpha particles following the {sup 6}Li(n,t){alpha} reaction are reported for incident neutron energies between 0.2 and approximately 20 MeV. The neutrons were produced by spallation at the WNR facility at the Los Alamos Neutron Science CEnter (LANSCE), with the incident neutron energy determined by the time-of-flight method. Four E-{Delta}E telescopes were used at eight laboratory angles. These data have been incorporated into a prior R-matrix fit for the compound {sup 7}Li system, and result in an (n,t) reaction cross section that is 4% to 10% higher than previous evaluations in the 1-3 MeV incident neutron energy region.

Studying the role of nuclear structure effects in neutron-induced reactions using GEANIE at LANSCE

Conference Bernstein, L A ; Archer, D E ; Becker, J A ; ...

Efforts to model and measure absolute neutron-induced reaction cross sections have for the most part been limited by experimental techniques to neutron energies found in reactors and light-ion fusion reactions (i.e., t(d,n){alpha} etc.). This can in large part be attributed to the difficulty involved in making high-flux mono-energetic neutron beams with E{sub n} > 14 MeV. The result has been a lack of guidance for (n,xnypz{alpha}) reaction modeling for E{sub n} > 1-2 MeV. These limitations become particularly exacerbated in nuclei where structure effects (i.e., near shell closures, high deformation etc.) or fission complicates the models. The GEANIE spectrometer atmore »« less

$sup 6$Li(n,t)$sup 4$He differential cross sections between 0.1 and 1.8 MeV

Journal Article Overley, J C ; Sealock, R M ; Ehlers, D H - Nucl. Phys., A, v. A221, no. 3, pp. 573-592

Absolute triton and alpha -particle yields from the /sup 6/Li(n,t)/sup 4/He reaction were measured at 8 lab angles between 0 deg and 90 deg for neutron energies between 0.1 and 1.8 MeV. Incident neutrons with a continuous energy distribution were used, and reaction yields were measured as a function of detected particle energy and the sum of particle-plus-neutron flight times. Yield data were converted to (n,t) c.m. differential cross sections at 16 angles between 0 deg and 180 deg . Each of the 25 angular distributions obtained was fitted to a series of Legendre polynomials. The coefficients of the P/submore »« less
48Ti(n,xnypz{alpha}{gamma}) Reactions for Neutron Energies up to 250 MeV

Journal Article Dashdorj, D ; Lawrence Livermore National Laboratory, Livermore, CA 94550 ; Garret, P E ; ... - AIP Conference Proceedings

Cross-section measurements were made of prompt {gamma}-ray production as a function of incident neutron energy on a 48Ti sample. Partial {gamma}-ray cross sections for transitions in 45-48Ti, 44-48Sc, 42-45Ca, 41-44K, and 41-42Ar have been determined. Energetic neutrons were delivered by the Los Alamos National Laboratory spallation neutron source located at the LANSCE/WNR facility. The prompt-reaction {gamma} rays were detected with the large-scale Compton-suppressed germanium array for neutron-induced excitations (GEANIE). Neutron energies were determined by the time-of-flight technique. The {gamma}-ray excitation functions were converted to partial {gamma}-ray cross sections taking into account the dead-time correction, target thickness, detector efficiency, and neutronmore »« less

{sup 48}Ti(n,xnpa{gamma}) reaction cross sections using spallation neutrons for E{sub n} = 1 to 20 MeV

Technical Report Dashdorj, D ; Mitchell, G E ; Garrett, P E ; ...

{gamma}-ray excitation functions have been measured for the interaction of fast neutrons with {sup 48}Ti (neutron energy from 1 MeV to 250 MeV). The Los Alamos National Laboratory spallation neutron source, at the LANSCE/WNR facility, provided a ''white'' neutron beam which is produced by bombarding a natural W target with a pulsed proton beam. The prompt-reaction {gamma} rays were measured with the large-scale Compton-suppressed Ge spectrometer, GEANIE. Neutron energies were determined by the time-of-flight technique. Excitation functions were converted to partial {gamma}-ray cross sections, taking into account the dead-time correction, the target thickness, the detector efficiency, and neutron flux (monitoredmore »« less
