✦ Synopsis

Doppler broadening lineshapes and positron annihilation characteristics \vcro determined as a function of additive concentration in aqueous solutions of se!ected silver and sodium salts. Evidence is presented that indicates that positronium formation and reactions are affected by anions, and that Fs interacts diFfcrent:y with Cl-and S,Og-, than with NO;, CIO;, and CIO,. Multi-parameter measurements may distinguish between the mechanisms of triplet-single: spin conversion and chemical reactions. * Resezch crrried out at BNL under contract <'ith the U.S.
