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