Capabilities and plans for preequilibrium nuclear reaction measurements at target-4 at LAMPF (Los Alamos Meson Physics Facility)
The Target-4 neutron source at the Los Alamos Meson Physics Facility (LAMPF) has recently been commissioned and used as a )open quotes)white)close quotes) source of fast neutrons from 1 to 500 MeV. A 90-meter flight path at a neutron production angle of 15 degrees has been characterized for neutron flux and spectral shape. The flux and shape agree well with calculated values showing that this is indeed an intense and useful white neutron source. Initial measurements of the /sup 12/C(n,p) reaction at forward angles have been made in the energy range 50 to 500 MeV. The results point the way to improve detector schemes and to a program of (n,p) cross section measurements in the energy range where preequilibrium processes dominate much of the charged-particle emission spectra. 3 refs., 2 figs
