STUDIES OF SOLIDS AT LOW TEMPERATURES

Abstract

Radical species which are stable only at low temperatures are investigated by electron spin resonance and optical methods. The initial compound chosen for study was KH2PO4, the deuterated compound also being included in this investigation. 50-kv x-rays produce free radicals in this compound which appear to be completely stable at liquid air temperatures, but decay rapidly above about 140K. Complete orientation data were taken on this compound about all three crystallographic axes for both undeuterated and deuterated crystals.
