摘要：

A class of deep centers in semiconductors is identified by their photoionization spectra, which have a narrow peak near the threshold energy and a broader peak at higher energy. The M center in ZnSe is an example. An explanation of the spectral shape is given in terms of a wave function with a radial node. Such wave functions can occur when a substantial contribution to the function comes from nearest-neighbor atoms.
