General formulae of the second order perturbation energies due to tensor force are given in case closed shell+one nuclei, and useful for calculating two-body matrix elements also derived. Using these formulae, D-state doublet splitting O17 is estimated it found that about a half observed value explained terms effect as He5 N15.
The intrinsic state of the Nilsson model is analyzed in terms nucleon pairs coupled to spins ${0}^{+}$, ${2}^{+}$, ${4}^{+}$, ${6}^{+}$,.... It shown that ${0}^{+}$ and ${2}^{+}$ dominate Cooper pair which constitutes with large quadrupole deformation.
The magnetic form factor of $^{17}\mathrm{O}$ is studied by taking account the effects core polarization and mesonic exchange currents. It shown that $M3$ part singleparticle value strongly canceled out polarization.
The quasi-spin formalism is used to derive useful reduction formulae for the shell model matrix elements two-body scalar interactions between states having same seniority quantum number. Several convenient are also derived in mixed configurations both degenerate and non-degenerate cases. violating component Wigner interaction estimated its range dependence investigated.
The $\mathrm{sdg}$ interacting-boson model is applied to $^{168}\mathrm{Er}$. Energy levels and $E2$ transitions are calculated. This shown solve the problem of anharmonicity regarding excitation energy first ${K}^{\ensuremath{\pi}}={4}^{+}$ band relative that ${K}^{\ensuremath{\pi}}={2}^{+}$ one. level scheme including ${K}^{\ensuremath{\pi}}={3}^{+}$ well reproduced calculated $B(E2)$'s consistent with experimental data.
Isoscalar giant quadrupole resonances are theoretically studied for $^{16}\mathrm{O}$ and $^{40}\mathrm{Ca}$. A remarkable difference in the widths of these observed ($\ensuremath{\alpha}, {\ensuremath{\alpha}}^{\ensuremath{'}}$) experiments is explained. Both one-particle, one-hole two-particle, two-hole correlations found to be responsible producing difference.
We suggest that two-nucleon transfer reactions be treated within the framework of SU(6) boson model. derive corresponding intensity rules in vibrational, SU(5), and rotational, SU(3), limit. show failure pair vibrational model accounting for observed intensities is due to neglecting finite dimensionality proton neutron shells.NUCLEAR REACTIONS Two-nucleon transfer, model, given rotational
