摘要: Abstract The level structures of the N = 50 83As, 82Ge, and 81Ga isotones have been investigated by means multi-nucleon transfer reactions. A first experiment was performed with CLARA–PRISMA setup to identify these nuclei. second carried out GASP array in order deduce γ-ray coincidence information. results obtained on high-spin states such nuclei are used test stability shell closure region 78Ni ( Z 28 ). comparison experimental schemes shell-model calculations yields an energy gap value 4.7(3) MeV at . This value, a good agreement prediction finite-range liquid-drop model as well recent large-scale calculations, does not support weakening down
