Abstract
Spectroscopic factor sum rules for single nucleon transfer are studied in the context of the interacting boson-fermion model. These sum rules are applied to pickup and stripping reactions on even-even targets. It is shown that for such targets the odd-even interacting boson-fermion model intermediate states are essentially complete, so that the evaluation of these sum rules using interacting boson-fermion model wave functions and transfer operators is valid. However, this is not true for reactions on odd-even targets. The interacting boson-fermion model sum rules are derived and applied to experimental data from recent studies of the platinum isotopes. A significant discrepancy exists between experiment and theory.
