Band structure of 85Sr

Abstract

High spin states in 85Sr were populated using the reaction 76Ge(13C, 4n) at a beam energy of 52 MeV. Gamma-gamma coincidence measurements along with investigation of directional correlation ratios were utilized to establish the extended level scheme upto I π=(35/2-). One of the positive parity states observed at 3383.3 keV ((Iπ=19/2(+)) may be considered as a magnetic rotational (ΔI=1) band, the negative parity states built on 3028.0 level show an irregular behaviour and does not exhibit magnetic rotation. © 2010 American Institute of Physics.
