The effect of uniaxial compression at 80K upon the formation efficiency of stable radiation defects in these crystals was investigated by means of absorption spectroscopy. It was found that compression along <100> directions did not alter the efficiency of radiation defect formation in KCl and KBr crystals while, in KI, the efficiency fell by more than an order of magnitude. It was concluded, on the basis of a semi-quantitative analysis, that the observed difference could be attributed to the impossibility of H centers fitting into the compression-reduced interstitial voids in KI. Several multiples of 10% compression were required in order to produce the same effect in KCl and KBr.
