In-Beam Study of 122,124,126Xe

Abstract
Excited states in 122,124,126Xe have been studied with the (3He, 3n) reaction using enriched Te targets and in-beam γ-ray and conversion electron spectroscopy. The existing information on the positive-parity levels is enriched and many new negative-parity states are established. A new 7- isomeric state is observed in 126Xe with a half-life of 1.9(5) ns. Interacting boson model (IBA-1) calculations have been performed to explain the collective level structures.
