  • A large-solid-angle array has been used to determine the multiplicity of Z = 1 and Z = 2 particles accompanying projectile breakup into two fragments each with 5less than or equal toZless than or equal to8. The charge balance obtained shows that projectile breakup is not associated with an unusual charge transfer to the target.
  • Coincidence measurement was made in the reaction /sup 40/Ca(/sup 20/Ne,/sup 16/O..cap alpha..) at 260 MeV incident energy, and the experimental results were analyzed in terms of the projectile breakup scheme. The reaction can be conveniently classified into the elastic- and inelastic-breakup processes. Comparison of the present results to those of the /sup 16/O-singles measurement indicates the importance of the process in which the breakup is followed by the fusion process. Theoretical analysis shows that the main aspects of the present experimental results are explained.
  • Experimental data on emission of particles with 2< or =Z< or =4 obtained at Dubna are analyzed within the framework of the Serber model, modified so as to describe the two-stage character of the breakup reaction and to estimate absolute values of production cross sections for different isotopes. It is shown that the breakup of the ion projectile is the main mechanism of emission of intermediate-mass clusters. The estimated production cross sections for /sup 10/He are discussed from the point of view of its instability.
  • Fragment production has been studied as a function of the source mass and excitation energy in peripheral collisions of {sup 35}Cl+{sup 197}Au at 43 MeV/nucleon and {sup 70}Ge+{sup nat}Ti at 35 MeV/nucleon. The results are compared to the Au+Au data at 600 MeV/nucleon obtained by the ALADIN Collaboration. A mass scaling, by {ital A}{sub source}{approximately} 35 to 190, strongly correlated to excitation energy per nucleon, is presented, suggesting a thermal fragment production mechanism. Comparisons to a standard sequential decay model and the lattice-gas model are made. Fragment emission from a hot, rotating source is unable to reproduce the experimental sourcemore » size scaling. {copyright} {ital 1996 The American Physical Society.}« less
