REGULAR SPIN SPLITTING OF (N,P) REACTION CROSS-SECTIONS ON TELLURIUM ISOTOPES

Partial cross sections of eleven (n,p) reactions on tellurium isotopes with A = 122 - 130 are measured for a neutron energy of 14.6 +/- 0.2 MeV. It is shown that the effect of regular spin splitting of nuclear reaction cross sections is manifested in the experimental data. The ob served local violation of regularity in splitting on Te-124 is interpr eted as the influence of a peculiar structure of the product nucleus ( Sb-124) on isotope systematics of the measured cross sections. It is f ound that isotope systematics of the cross sections of reaction Te(n,p )Sb for E(n) = 14.6 MeV and reaction Sn(p,n)Sb for E(p) = 6 - 9 MeV ar e similar.
