Mixed target ground-state effects in single-nucleon transfer to odd-odd nuclei

The effect of a mixed target ground state is considered when populating states in an odd-odd nucleus via single-nucleon transfer. Expressions for the spectroscopic strength for stripping and pickup reactions have been derived assuming that the target is described by a combination of Nilsson orbitals and final states are mixed configurations. The mixing causes the transfer strength to be spread out over many levels and, even with moderate mixing …
