Microscopic analysis of T=1 and T=0 proton-neutron correlations in $N = Z$ nuclei

M. Hasegawa, K. Kaneko

The competition between the isovector (T=1) and isoscalar (T=0) proton-neutron ( $p - n$ ) correlations in $N = Z$ nuclei is investigated by calculating their correlation energies with a…

Shape transition and oblate-prolate coexistence in N=Z fpg-shell nuclei

K. Kaneko, M. Hasegawa, T. Mizusaki

Nuclear shape transition and oblate-prolate coexistence in $N = Z$ nuclei are investigated within the configuration space ( $2 p_{3/2}$ , $1 f_{5/2}$ , $2 p_{1/2}$ , and $1 g_{9/2}$ ). We per…

Particle alignments and shape change in $^{66}$ Ge and $^{68}$ Ge

M. Hasegawa, K. Kaneko, T. Mizusaki

The structure of the $N \approx Z$ nuclei $^{66}$ Ge and $^{68}$ Ge is studied by the shell model on a spherical basis. The calculations with an extended $P + QQ$ Hamiltonian in the co…

Proton-neutron alignment in the yrast states of $^{66}$ Ge and $^{68}$ Ge

M. Hasegawa, K. Kaneko, T. Mizusaki

The $^{66}$ Ge and $^{68}$ Ge nuclei are studied by means of the shell model with the extended $P + QQ$ Hamiltonian, which succeeds in reproducing experimentally observed energy levels…

Pairing transition of nuclei at finite temperature

K. Kaneko, M. Hasegawa

Pairing transition at finite temperature was investigated by the shell model and BCS calculations. The definitive signature of pairing transition is identified by a "transition tem…

Competition between isoscalar and isovector pairing correlations in N=Z nuclei

Kazunari Kaneko, Munetake Hasegawa

We study the isoscalar (T=0) and isovector (T=1) pairing correlations in N=Z nuclei. They are estimated from the double difference of binding energies for odd-odd N=Z nuclei and th…
