NUCLEAR-CHARGE DISTRIBUTIONS OF SEVERAL FISSION PRODUCT MASS CHAINS

摘要

New information on the nature of nuclear charge distribution in thermal neutron fission of 235U has been obtained from measurements of fission yields of the major constituents in each of three adjacent mass chains. A regular variation in the width of the charge distribution curves with mass number has been shown, and values of the most probable nuclear charge (Zp) have been determined. No effects attributable to the 50 proton or 82 neutron closed shells have been observed in the charge distribution curves examined.
