An Analv,sis of the Decay Properties of the F and M Centers in L i F Crystals By 1) 2 )
L. BOSI and M. MMISIn the last few years the ag'gregate centers in alkali halides have been extensively studied because of their importance in applied physics (for instance, laser physics). Furthermore, L i F crystals, pure and doped with suitable impurities, have been investigated and utilized f o r dosimetry.
