Description

The reaction rate of the $^{59}$Cu(p,$\gamma$)$^{60}$Zn has been identified to have a significant impact on the light curve of X-ray bursts, controlling the reaction flow out of the Ni-Cu cycle impacting the late-time light curve. The $^{58}$Ni($^{3}$He,n)$^{60}$Zn indirect measurement can be used to study the $^{59}$Cu(p,$\gamma$)$^{60}$Zn reaction. We are using the neutron evaporation spectrum from $^{58}$Ni($^{3}$He,n)$^{60}$Zn in order to extract the level density of $^{60}$Zn and constrain the $^{59}$Cu(p,$\gamma$)$^{60}$Zn reaction rate. To augment the ($^{3}$He,n) technique for lower level-density compound nuclides, a silicon detector array is being developed for use in determining charged-particle decay branching ratios from discrete states. The present status of data analysis and detector development will be discussed, as well as the future plans.
