Abstract.

Excited states of ⁶³Cu were populated via the ⁵²Cr + ¹⁶O (65 MeV) reaction using the gamma detector array equipped with charged particle detector array for reaction channel separation. On the basis of g-g coincidence relations and angular distribution ratios, a level scheme was constructed up to E_x =7 MeV and J ^p =23/2 ⁽⁺⁾. The decay scheme deduced was interpreted in terms of shell model calculations, with a restricted basis of the f_5/2, p_3/2, p_1/2, g_9/2 orbitals outside a ⁵⁸₂₈Ni core.

Keywords: Nuclear reaction ⁵²Cr (¹⁶O, a p)⁶³Cu at E = 65 MeV; measured Eg; I_g; g-g-charged particle coincidence; ⁶³Cu deduced levels; J ^p; DCO ratio; shell-model calculation.
