Absorption measurements were carried out on the (NV)– centers in diamond at low temperature after laser illumination. It was observed that the width of the zero-phonon line becomes persistently more than two times larger. This characteristic phenom

Optical transitions between excited states of impurities in germanium, Sb or As, in a magnetic field have been investigated using HCN, DCN and H20 lasers. The energy levels of states with even parity and M= +1, i.e., 3D+l, (113) and (115), are determ
