Level scheme of65Ga

  • Published:
Il Nuovo Cimento A (1971-1996)

Summary

The level scheme of65Ga has been studied up to an excitation energy of 7035.3 keV and spin-parity values of (27/2+). Gamma-ray singles, γγ-coincidences, angular distributions and Doppler shift attenuation have been measured in the reaction63Cu(α, 2nγ) at 30 MeV. The spin and parity (√π) assignments for several states belonging to the previously known bands are confirmed. The mean life and the parity of the 2814.7 keV state, hitherto unknown, are reported. The √π for the 3733.2 keV state is proposed to be 15/2+ on the basis of angular distribution data and its decay characteristics to the lower-lying states. Experimental evidence is presented in favour of the 3733.2 keV state of being a bandhead for a rotation-like ΔI=2 positive-parity band with the excited members at 4547.5, 5643.5 and 7035.3 keV. The deducedB(E2) results indicate the presence of appreciable collectivity in the other positive-parity band built on the 9/2+, 2037.3 keV state. These bands in65Ga are discussed and compared with similar bands in the neighbouring odd-A nucleus67Ga.
