Abstract: | The 68Zn(, α)66Cu reaction populating low-lying states in 66Cu has been studied at θlab = 4° using deuteron beams in the energy range 9.0 to 10.5 MeV. Tensor analyzing powers were calculated and natural- or unnatural-parity assignments were made for thirteen states in 66Cu. By combining these results with existing limits unambiguous Jπ assignments of 2+, 2+, 2+ and 1+ have been made for the levels at 186, 465, 822 and 1344 keV respectively. The previous tentative assignments to seven other levels have been confirmed while that for the 1247 keV level has been shown to be incorrect. The identification of the quartet of levels based on the configuration has been confirmed. |
