Absorption bands of Ho '\* in vitreous LazS3 -3GazS3 in the range 500 to 2000 nm were assigned. Excitation spectra reveal additional levels 5G6 and 5F3 obscured by the intrinsic absorption of the glass. The Ho3+ emission in chalcogenide glasses is more intense than in oxide gksses due to smaller non

The cross sections for the deexcitation of He(2 'S), He( 2 'S), and He{ 2 'P) by SiH, and GeH, have been measured and compared with those for the deexcitation by CH,. The major deexcitation processes are ascribed to Penning ionization. The cross sections obtained for He (2 'S) are more than two hund
