Description
The nuclear spin distribution defines the distribution of levels as a function of spin at a given excitation energy in a nuclear system. The spin distribution is virtually unmeasured in exotic neutron-rich nuclei and is a critical input for applications in nuclear technologies and astrophysics. With recent advances in analysis techniques, it is possible to determine model-independent partial level densities in some short-lived nuclei. The application of these analysis techniques following beta decay can provide a partial level density over a limited spin range. Combined with a means to produce and separate multiple beta-decaying states within the same nucleus with different spins, then a partial level density can be inferred within different spin windows. This provides a means to extract some of the first information on the spin distribution at high excitation energy in the resulting nucleus. The prospects of inferring the spin distribution following beta decay into $^{70}$Zn will be presented using data from the decay of isolated beta-decaying states in $^{70}$Cu: the 6$^{-}$ ground state and the 1$^{+}$ first excited state.
