MUONIUM STATES AND DYNAMICS IN PHOSPHORUS AND SULFUR

The various states formed by positive muons implanted into phosphorus and sulphur have been characterized as a model for interstitial hydrog en, of which little is known in these elements. Repolarization studies reveal muonium-like states in each case, giving estimates of the hype rfine parameters and, for sulphur at least, an indication of the coexi stence of a molecular radical state. The longitudinal-field relaxation functions suggest conversion of the paramagnetic states to diamagneti c, i.e. ionization or chemical reaction, in competition with strong sp in-lattice relaxation.
