A study of energy levels in odd-mass copper nuclei by means of the (alpha,p) reaction

Energy levels in Cu-61,Cu-63,Cu-65,Cu-67 have been studied by means of the three-particle transfer reactions Ni-58,Ni-60,Ni-62,Ni-64(alpha, P)(61,63), Cu-65,Cu-67. Differential cross sections have been measured in the angular range from theta = 7.5 degrees to theta = 77.5 degrees in steps of 5 degree s at an incident energy of 25 MeV. The protons were momentum analysed in a multigap magnetic spectrometer. Theoretical cross sections have been calcul ated using a semi-microscopic model. Spin and parity assignments of the ene rgy levels in Cu-67, assigned by comparison with experimentally determined angular distributions of previously well-known energy levels in Cu-61,Cu-63 ,Cu-65, and DWBA calculations.
