Conversion electron measurements of $^{195}$Au using ICEBall for Nuclear Structure and Astrophysics at the University of Notre Dame

The Internal Conversion Electron Ball Array (ICEBall)\footnote{M.P. Metlay, J.X. Saladin, I.Y. Lee, and O. Dietzsch, Nucl. Instrum. Meth. A, 336, 162 (1993)} consists of six Si(Li) detectors and it was recently re-comissioned\footnote{A. Battaglia et al. to be submitted} at the University of Notre Dame Nuclear Science Laboratory for spectroscopic studies of heavy nuclei. For the commissioning experiment, a 16 MeV bunched proton beam was used from the FN Tandem for a (p,2n) reaction to populate low spin states of $^{195}$Au. Both conversion electrons and gamma-rays were detected in coincidence between ICEBall and a single high-purity germanium detector. A total of 14 conversion coeffcients were measured. The results will be presented and compared to previous results.\footnote{S. M.
