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 ${}^{235}$U
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...

| Sumario: | 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 $ % $. |
