摘要：

Pusle-shape discrimination (PSD) techniques on current pulses from coaxial germanium detectors can significantly correct for charge losses due to hole trapping caused by radiation damage. Numerical simulations of PSD indicate that by measuring the two largest photon interaction locations and correcting the energy depositions separately, a significant recovery of the energy resolution and the Gaussian line shape of narrow lines in radiation damaged detectors can be obtained.
