Study of N=50 gap evolution around Z=32 : new structure information for ^82 Ge

Medium spin states of light N = 50 isotones have been populated using fast neutron-induced fission of ^232 Th. Online prompt γ spectroscopy has been performed using the hybrid γ spectrometer ν- Ball coupled to the LICORNE directional neutron source at the ALTO facility of IJCLab. Medium spin states of the neutron-rich nucleus ^82 Ge have been investigated using γ - γ and γ - γ - γ coincidence data to exploit the resolving power of ν- Ball. Two new transitions were assigned to this nucleus and a new level was placed in the level scheme. We tentatively assigned to this new state a ( 7^+ ) spin-parity, which is interpreted as a new N=50 core breaking state. This provides further insight into the energy evolution of the N=50 shell gap toward ^78 Ni.
