New Facilities

A progress report is given on the upgraded facilities at the Los Alamos Meson Physics Facility to support (p, n) and (n, p) charge-exchange studies at intermediate energies. These include a beam-swinger system, a 600 m flight path and neutron polarimeter for (p, n) reactions, and a medium-resolution spectrometer with a focal-plane polarimeter for (n, p). A general overview of the physics program being planned is also presented.

The nuclear isotopic structure can be understood easily via the intermediate-energy charge exchange reactions of (p, n) and [Formula: see text]He, [Formula: see text] type. In the current contribution, we present some results for charge exchange reactions induced by 3He on targets lying in mass region [Formula: see text] within the theoretical framework of plane wave impulse approximation (PWIA) and distorted wave impulse approximation (DWIA). Here, the recoil effects in PWIA have also been considered. Particularly, the angular distributions and the unit cross-sections have been calculated and compared with the available data. Further, the importance of inclusion of the exchange contribution in these reactions is also considered, which eventually enhance the matching with data.
