Yield of near-target product interaction of 47 MeV/A12C ions with bismuth targets

Formation cross sections of near-target products from the reaction of 47MeV/A¹²C with²⁰⁹Bi targets have been measured. Their independent yields were obtained from their cumulative and partially cumulative yields according to the experimental data measured in this work and correction for mother-daughter decay. From the yield distribution curves of Pt, Au and Hg isotopes constructed it was found that for their peak positions at mass numbers A=188.1, 190.9 and 195.8, the widths of charge distributions are = 3.08, 2.80 and 3.74, respectively. The formation cross sections for some near-target neutron-rich new isotopes were extrapolated from the isotopic yield distribution curves.
