Spectra of luminescence of inert gases mixes with NF3 and CCl4 -particles of Α are investigated at excitation by 210Po. Spectra consist of several bands, the most intense band is identified as B-X transition. For Ar (1.5 atm) + Xe (40 Torr) + CCl4 (0.7 Torr) mixture the factor of transformation of a nuclear energy into emission in a band of 308 nm is appreciated: η ~ 11%.
