TITLE=/ Neutron yields from thick C, Al, Cu, and Pb targets
bombarded by 400 MeV/nucleon Ar, Fe, Xe and 800 MeV/nucleon Si
ions /;
PURPOSE=/ To perform a systematic study to measure the double
differential neutron yields from thick targets of C, Al, Cu,
and Pb bombarded by various heavy ions having energies of
100 to 800 MeV/nucleon using HIMAC. /;
