High Spin Level Structure in 153Dy and Shape Changes in Neutron-Deficient Dy Nuclei
- Received Date: 1990-07-04
Abstract: High spin state in 153Dy is studied up to 81/2 h through the in-beam γ-ray spectroscopy technique. The reaction of 122Sn (36S, 5n) is used at a beam energy of 165 MeV. Above the I=47/2 h isomeric state, complex single-particle structure is dominant along the yrast line and in its close vicinity. Nuclear shape changes of neutron deficient Dy isotopes with neutron number N and spin I are discussed.
