Modification of triaxial deformation and change of spectrum in ${}_{\Lambda }^{25}$Mg caused by $\Lambda$ hyperon

Masahiro Isaka, Hiroaki Homma, Masaaki Kimura +2

The positive-parity states of ${}_{\Lambda }^{25}$Mg with a $\Lambda$ hyperon in $s$ orbit were studied with the antisymmetrized molecular dynamics for hypernuclei. We discuss two bands of $^{2…
