Abstract

The high-spin structure of ¹⁰⁹In has been investigated with the ¹⁰⁰Mo(¹⁴N, 5n)¹⁰⁹In reaction at a beam energy of 78 MeV using the in-beam \ensuremathγ spectroscopic method. The level scheme of ¹⁰⁹In has been modified considerably and extended by 46 new \ensuremathγ rays to the highest excited state at 8.980 MeV and J^\ensuremathπ=(45/2⁺). The new level scheme consists of eight bands, six of which are identified as dipole bands. The configurations have been tentatively assigned with the help of the systematics of neighboring odd-A indium isotopes and the experimental aligned angular momenta. The dipole bands are then compared with the titled axis cranking calculation in the framework of covariant density function theory. The results of theoretical calculations based on the configurations, which involve one proton hole at the g_9/2 orbital and two or four unpaired neutrons at the g_7/2, d_5/2, and h_11/2 orbitals, show that the shape of ¹⁰⁹In undergoes an evolution on both \ensuremathβ and \ensuremathγ deformations, and possible chirality is suggested in ¹⁰⁹In.
