Journal ArticleDOI
Magnetic moments and GT-type β-decay matrix elements in nuclei with a LS doubly closed shell plus or minus one nucleon
K. Shimizu,M. Ichimura,A. Arima +2 more
TL;DR: In this article, the magnetic moments and GT-type β-decay matrix elements of nuclei were studied from the point of view of configuration mixing in terms of second order perturbation theory.
Journal ArticleDOI
Four-nucleon transfer reactions among heavy ions
TL;DR: In this article, an effective potential Veff between the transferred α-particle and the core nucleus was chosen, and the influence of different choices for Veff was discussed and the results for the post and prior forms are compared.
Journal ArticleDOI
Stabilization of the axially symmetric shape and (pf)2 mixing in sd shell nuclei
TL;DR: Two-particle excitations into the pf shell from the sd shell is shown to be important to make nuclei such as 22 Ne and 24 Mg more axially symmetric.
Journal ArticleDOI
The structure of positive parity states of 20Ne
TL;DR: In this article, the positive parity spectrum of 20Ne was studied using a complete sd basis with additional two-and four-hole states, and the effect of promoting two particles to the 2p-1f shell was also examined.
