High spin states in 52Mn and 54Mn

The present experiment was carried out at HI-13 tandem accelerator of the China Institute of Atomic Energy in Beijing. High spin states in 52Mn and 54Mn, were populated via 12C+48Ti fusion evaporation reactions at beam energy of 60 MeV. Gamma-gamma coincidence experiment was performed with an array consisting of fourteen Compton suppressed HPGe-BGO spectrometers. Level scheme of 52Mn and 54Mn has been established in this experiment, In order to understand the insight structure of the high spin states of 52Mn observed in present work, we have performed OXBASH shell model calculations, the results agree with the experimental results.
