YIELD OF NEAR-TARGET PRODUCT INTERACTION OF 47 MEV A C-12 IONS WITH BISMUTH TARGETS/

Formation cross sections of near-target products from the reaction of 47MeV/A C-12 with Bi-209, targets have been measured. Their independen t yields were obtained from their cumulative and partially cumulative yields according to the experimental data measured in this work and co rrection for mother-daughter decay. From the yield distribution curves of Pt, Au and Hg isotopes constructed it was found that for their pea k positions at mass numbers A = 188.1, 190.9 and 195.8, the widths of charge distributions are sigma(Z) = 3.08, 2.80 and 3.74, respectively. The formation cross sections for some near-target neutron-rich new is otopes were extrapolated from the isotopic yield distribution curves.
