Systematics of Complex Fragment Emission in Niobium Induced Reactions

摘要

Complex fragments of 3 < Z ) < approx 35 have been detected in the reverse-kinematics reactions of sup 93 Nb plus sup 9 Be, sup 12 C and sup 27 Al at bombarding energies of EA = 11.4, 14.7 and 18.0 MeV. Velocity spectra and angular distributions show the presence of projectile and target-like components along with a component isotropic in the reaction plane. This latter component appears as a Coulomb ring in the invariant cross section plots indicating the presence of a binary decay which is confirmed by the coincidence data. 6 refs., 6 figs.
