BINDING OF D- IONS IN A MAGNETIC-FIELD

I present the first strong evidence for the observation of D- centers in a semiconductor with a simple conduction band minimum at k=0. The identification is based primarily upon agreement between the predicted and observed curve of photodetachment threshold frequency vs magnetic field in CdS. New, relatively simple and physically motivated variation trail functions are employed which give eigenvalues of sufficient accuracy for critical comparison with experiment. © 1979 The American Physical Society.
