Investigating Nuclear Structure Relevant to Neutrinoless Double Beta Decay

Benjamin P. Kay, Argonne National Laboratory
Building 6008 Conference Room

Disagreements between theoretical predictions of matrix elements relevant to neutrinoless double beta decay have motivated our measurements of the differences in valence occupations in the ground states of 76Ge and 76Se. Results from neutron adding/removing reactions indicate that the Fermi surface is much more diffuse than theoretical calculations suggest. Recently, similar measurements have also been carried out to determine the difference in proton occupations of these nuclei. This program of work is complemented by results probing pair correlations in these nuclei, obtained using the (p,t) reaction. Methods and results will be discussed.
