Mass yield distributions in proton-induced fission of²⁴⁸Cm

Mass yield distributions in the proton-induced fission of ²⁴⁸Cm are measured by a radiochemical method in the proton energy range of 10.5-20.0 MeV. The resulting mass yield distributions are typically asymmetric and gross features of the distributions are independent of the excitation energy studied. Systematic trends of the mass yield distributions in low-energy proton-induced fission of actinides are discussed in terms of weighted mean mass numbers of the light and heavy asymmetric mass yield peaks, and widths of the heavy asymmetric mass yields.
