【 摘 要 】

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