Abstract

Excited states of the neutron deficient nucleus Te109 were identified for the first time in the Fe54(58Ni,2pn) reaction by in-beam γ-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 γ rays. A level scheme was constructed on the basis of γγ-coincidence relations, and the angular momenta of the states were determined from the measured angular correlation intensity ratios. Two favored bands built on the νg7/2 and νh11/2 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.
