Excited states with Λ hyperon in p-orbit in MgΛ25

The excited states of MgΛ25 with the Λ hyperon in p-orbit are studied with the antisymmetrized molecular dynamics for hypernuclei. Three rotational bands are obtained by adding a Λ in a p-orbit to the ground band of 24Mg. It is found that these bands energetically split due to the triaxial deformation of the core nucleus 24Mg and the spatial anisotropy of the p-orbits of Λ.
