OSTI ID:7244005
The reaction mechanisms responsible for the production of light charged particles and heavy fragments have been investigated for a 5560-MeV lanthanum beam from the Lawrence Berkeley Laboratory BEVLAC incident on targets of La, /sup 27/Al, and /sup 197/Au. The inclusive kinetic energy spectra of particles with Z = 1 to 5 are characteristic of sequential emission from projectile-like fragments (PLF). Coincidence measurements between light charged particles (LCP) and heavy fragments indicate that the LCP's are predominately emitted from fragments with Z < 30. Alpha-to-proton ratios for very forward angles in the laboratory are greater than predicted using evaporation models. Possible explanations for these ratios may be kinematic focussing and/or emission from sources ( Z< 16) which favor the emission of alpha-particles.
