High-spin spectroscopy of {sup 109}Te
Excited states of the neutron deficient nucleus {sup 109}Te were identified for the first time in the {sup 54}Fe({sup 58}Ni,2{ital pn}) reaction by in-beam {gamma}-spectroscopic methods. The NORDBALL detector array, equipped with a charged-particle and a neutron detector system for reaction channel identification, was used to detect the evaporated particles and {gamma} rays. A level scheme was constructed on the basis of {gamma}{gamma}-coincidence relations, and the angular momenta of the states were determined from the measured angular correlation intensity ratios. Two favored bands built on the {nu}{ital g}{sub 7/2} and {nu}{ital h}{sub 11/2} neutron quasiparticle states were identified. The structure of the nucleus is discussed in the framework of the particle-vibration coupling model using the interacting boson-fermion formalism up to spin 27/2. The negative parity sequence is compared to Total Routhian Surface calculations.
