Study of the excited states of ⁶⁰’⁶¹Zn

Abstract

<p>The level structures of the nuclei ⁶⁰Zn and ⁶¹Zn have been studied by means of (τ,nϒ) and (α,nϒ) reactions, respectively. Additional heavy ion induced reactions were also investigated with respect to ⁶⁰’⁶¹Zn and other competing channels, notably ⁵⁹Zn , ⁶⁰Cu and ⁶¹Ga. Gamma singles, n-ϒ coincidence, ϒ-ϒ, multi-y coincidence, ϒ and n-ϒ angular distribution measurements were made. Limitations on excited state lifetimes were obtained from beam pulsing, electronic timing, and Doppler shift measurements. A high resolution neutron spectrum of the ⁵⁸Ni(α,n)⁶¹Zn reaction was obtained. Attempts at other multi-particle transfer experiments have been unsuccessful.</p> <p>The experimental results are compared with those found elsewhere and with theoretical calculations.</p>
