Systematic Effects on Pulse Shape Analysis in HPGe Detectors for 0$\nu\beta\beta$ Searches

The M{\sc ajorana} Project will endeavor to provide direct limits on the effective Majorana mass of the electron neutrino through the measurement of neutrinoless double-beta decay in $^{76}$Ge. One of the techniques that the M{\sc ajorana} experiment will implement to separate single-site energy depositions (such as 0$\nu\beta\beta$ or 2$\nu\beta\beta$ events) from multi-site events (such as multiply scattering $\gamma$ rays) is pulse shape analysis. We present work performed at Los Alamos National Laboratory using a ``CLOVER'' detector (a close-packed array of four 800g, two-fold segmented natural germanium detectors) to characterize systematic uncertainties in the survival probabilities of double-escape, Compton continuum and full-energy $\gamma$ ray events under two-moment parametric pulse shape cuts.
