TITLE=/ Measurements of secondary neutrons produced from thick
targets bombarded by high-energy helium and carbon ions /;
PURPOSE=/ To present the angular and energy distributions of
neutrons produced from thick C, Al, Cu, and Pb targets
bombarded by 100 and 180 MeV/nucleon He and 100, 180, and
400 MeV/nucleon C ions. /;
