Fission-Fragment Anisotropy in Reactions of 24-MeVH2and 48-MeVHe

Mass asymmetry dependence of angular distribution in237Np(?29 and 44 MeV,f): single particle effect

“…and 23Su(c~29 a,a 39 MeV, f) systems. Variation of angular anisotropies of fission products with mass asymmetry was earlier reported by Cohen et al [16] in 22MeV 1H induced fission of 232Th and 233,235.238 U, Viola et al [13] in 22MeV 1H, 24MeV ZH and 48 MeV 4He-ion induced fission of 23Su as well as Kudo et al [11] in 232Th(pa5 Mev, f) systems. No correlation was seen however in 42 MeV r induced fission of the preaetinides 2~…”

“…In the present work angular distributions were measured for various mass asymmetric fission products in the odd-Z systems 237 Np (~29 and 4-4 MeV, f)" Present data were analysed along with the literature data for several odd-Z or A preactinides and actinides [2,3,[7][8][9][10][11][12][13]. On the basis of TSM [1,2] and two-mode hypothesis [4,14], angular distributions are seen to be correlated to mass asymmetric configurations in 241Am fission.…”
