TL;DR: In this article, an attempt has been made to analyse the data on the last nucleon binding energies of transuranic elements and some interesting results are obtained regarding the behaviour of the λ term introduced by Ghoshal.
Abstract: An attempt has been made to analyse the data on the last nucleon binding energies of transuranic elements. Some interesting results are obtained regarding the behaviour of the λ term introduced by Ghoshal. Some confirmatory evidence is also obtained regarding the sub-shell at N = 152.

TL;DR: In this article, the authors analyzed proton and neutron binding energies in such a way as to permit an approximate assessment of the effects associated with pairing and shell structure and drew several interesting conclusions with respect to the accuracy of various theoretical expressions which have been proposed for the pairing effect.
Abstract: Proton and neutron binding energies are analyzed in such a way as to permit an approximate assessment of the effects associated with pairing and shell structure. We draw several interesting conclusions with respect to the accuracy of various theoretical expressions which have been proposed for the pairing effect. Our analysis of the data and considerations of an atomic model lead us to a simple approximate representation of a shell stabilizing correction to nuclear energies. This shell structure term accounts rather well for the observed departures from the general trends of beta-stability, nuclear masses, and nuclear $Q$ values. Our shell correction suggests that much larger systematic variations in nuclear masses may be identified with shell structure effects than might previously have been suspected.

TL;DR: In this article, the effect of pairing interaction between the last odd neutron and last odd proton in the outermost neutron and proton shells of a nucleus has been demonstrated by the last neutron binding energy and the last proton binding energy plots in the heavy nuclei.
Abstract: The effect of neutron-proton pairing interaction between the last odd neutron and the last odd proton in the outermost neutron and proton shells of a nucleus has been demonstrated by the last neutron binding energy and the last proton binding energy plots in the heavy nuclei. The n-p pairing interaction has been estimated for nuclei in the region Z>82 and N>126 and it has been successfully used to explain the neutron and proton binding energy plots. The interaction energy seems to decrease with increase in the difference between neutron and proton numbers in the outermost neutron and proton shells respectively for nuclei in the region of Z>82 and N>126.

TL;DR: In this paper, the variations of neutron-proton interaction among the ''outer'' nucleons which are indicated by the experimental binding energies are compared with calculations of the energies of the lowest states of configurations of neutrons and protons suggested by the jj-coupling shell model and experimental data on spins and magnetic moments.
Abstract: Variations with N and Z of nuclear binding energies in the radioactive region are compared with calculations of the energies of the lowest states of configurations of neutrons and protons suggested by the jj-coupling shell model and experimental data on spins and magnetic moments. Attention is given to the variations of neutron-proton interaction among the `outer' nucleons which are indicated by the experimental binding energies.
