Signature dependent triaxiality for shape evolution from superdeformation in rapidly rotating ${}^{40}$Ca and ${}^{41}$Ca

Shinkuro Sakai, Kenichi Yoshida, Masayuki Matsuo

We investigate the possible occurrence of the highly-elongated shapes near the yrast line in ${}^{40}$Ca and ${}^{41}$Ca at high spins on the basis of the nuclear energy-density functi…
