The two reactions, ⁶⁰Ni(α,nΥ) ⁶³Zn (Eα=12.0 Mev) and ⁶⁴Zn(p,d) ⁶³Zn (Ep=18.0 Mev) were studied.
Υ angular distributions and Υ-Υ coincidence yields were extracted and correlated to ascertain the ⁶³Zn decay scheme. ℓ values and spectroscopic factors were determined from DWBA fits to the neutron pickup cross sections. The following spin and parity assignments were made to the low-lying states of ⁶³Zn: E=626.5 kev (J^π=1/2ˉ,3/2ˉ,5/2ˉ), E=637.0 kev (J^π=7/2ˉ), E=650.0 kev (J^π=5/2ˉ), E=1023.2 kev (J^π=3/2ˉ), E=1206.4 kev (J^π=7/2ˉ), E=1284.8 kev (J=5/2), E=1436.7 kev (J=3/2,5/2), E=1703.8 kev (J=7/2), E=1861.6 kev (J=7/2). E=2050.8 kev (J=9/2). A level at 1392.4 kev was observed in the (p,d) experiment. The state at 1063.9 kev was observed to be a doublet, with a separation of less than 1.5 kev (J^π=7/2ˉ, J^π=(1/2ˉ)).
