“…This is in contradiction with the reported [13] p-ray branchings for this state (see Table I The level scheme up to 3.23 MeV in excitation was first reported by Nilsson and Sawa [3] while Neal et al [13] have reported levels extending up to 5.42 MeV. The pp-coincidence relationships observed in this work corroborate the placements of all previously known transitions in the level scheme (Fig.…”

“…This result is less than the values reported earlier in Refs. [11,12] but nevertheless shows agreement within experimental errors with the result of Neal et al [13]. In the present work the relative intensity for the 749.1 keV decay is deduced &om a comparison of the relative intensity of this p ray with that of the 864.…”

“…The 3227.6 keV state, which was previously proposed to have J & 13/2, is found to decay by a pure quadrupole 1174.1 keV transition, restricting the spin and the parity of the level to 17/2+. Contributions in the yields of the 1174.1 keV p ray due to interferences &om neighboring p-ray lines belonging to ' Ni, reported to be considerably large in the reaction employed in the earlier work [3,13], were found to be small (less than 5%) in this work and have been appropriately accounted for in the analyses. For the 3785.7 8) analyses favor the J assignment of 17/2+, although 13/2+ is not ruled out.…”

Measurements of p-ray singles and pp-coincidence spectra, p-ray angular distributions, and Doppler shift attenuation have been made, following the reaction Cu( He,pa) Zn at 30 MeV. The level scheme has been con6rmed up to 5773 keV. The spins and parities of the three states at 3227.6, 3785.7, and 4938.0 keV, hitherto uncertain or unknown, are found to be 17/2+, 17/2+, and 21/2+, respectively. The mean lives for these states, for which there is no information available in the literature, have been estimated, and the deduced B(Z2) values for the 4938.0-+ 3227.6 (21/2+~17/2+), 3227.6 m 2053.5 (17/2+ -+ 13/2+), and 3785.7 -+ 2053.5 (17/2+~13/2+) keV transitions are all found to be strongly enhanced with respect to the Weisskopf single-particle estimates indicating collectivity in the structure of the concerned states. Evidence is presented in favor of the interpretation of the positive parity states in Zn with J value 9/2+ to 21/2+, as arising from the weak coupling of a g9/2 neutron to the quadrupole excitations of the Zn core.

“…The low-spin structure of the odd-nucleus Zn has been studied previously using both alpha induced reactions [5,6] and various transfer reactions [7][8][9]. No heavy-ion induced reaction has been attempted to explore the high-spin states for this nucleus.…”
