A new limit has been set on neutrinoless double beta decay, a process which would require lepton number nonconservation, plus one other piece of new physics. That second item might be light Majorana electron neutrino mass, a very heavy Majorana neutr

This paper present some of the less recognized and potentially important parameters of the electronics and detectors used in X-ray fluorescence spectrometers. Detector factors include window (dead-layer) effects, time-dependent background and excess

The usual requirement for a spectrometer system is to provide the best energy resolution that can be obtained with a set of given experimental constraints. These constraints can change with each experiment, and the experimenter should be able to opti

A broad review of the physics of point defects, i.e. electrically active and neutral impurities and impurity complexes is given. Basic material science which is crucial for understanding the physics is summarized in an introductory section. It is fol

A new kind of position-sensitive germanium detector based on a novel mode of charge transport is proposed and experimental devices have been fabricated. In these germanium "drift-chambers", position information is obtained by measuring carrier drift
