POSITIVE EVEN-ODD EFFECTS IN THE MAXIMAL KINETIC ENERGY AND NEGATIVE EVEN-ODD EFFECTS IN THE MINIMAL EXCITATION ENERGY OF FRAGMENTS FROM THERMAL NEUTRON INDUCED FISSION OF 235U

摘要

Based on the Coulomb effect hypothesis it is shown that positive even-odd effects of the maximal total kinetic energy (Kmax) and negativeeven-odd effects of the total minimal excitation energy (Xmax), as a function of charge (Z) and neutron number (A) of fragments,respectively, are not in contradiction. According to the Coulomb effect hypothesis, Kmax is equal to the maximal Coulomb interactionenergy (Cmax) reached by the most compact scission configuration. The fragmentation corresponding to Z = 41 and A = 103 is an exceptionalcase for which scission configuration is formed by complementary fragments in their corresponding ground states. However, moresymmetrical o more asymmetrical fragmentations than that need to be out of their ground states, which implies that Kmax = Cmax < Q
