High spin spectroscopy of Pr-139

The high spin states in N = 80 Pr-139 have been investigated by in-beam gam ma -spectroscopic techniques following the reaction Te-130 (N-14, 5n) react ion at E = 75 MeV, using a gamma detector array, consisting of seven 23% co mpton-suppressed high purity germanium detectors and a multiplicity ball of fourteen bismuth germanate elements. Based on gamma-gamma coincidence data , the level scheme of 139Pr has been considerably extended up to 7.2 MeV ex citation. Tentative spin-parity assignments are done for the newly proposed levels on the basis of the DCO ratios corresponding to strong gates and th e available information from the earlier light ion experiments.
