nuclear reaction products in the core of a nuclear reactor. Lithium was deposited on walls of experimental cell in the form of a
capillary-porous structure, which made it possible to measure up to a temperature of 730 K. 'e temperature dependence of the
radiation intensity of noble gas atoms, alkali metals, and heteronuclear ionic noble gas molecules was studied. Also, as in the case of
single-component gases, the appearance of lithium lines and impurities of sodium and potassium is associated with vaporization
during the release of nuclear reaction products from the lithium layer. 'e excitation of lithium atoms occurs mainly as a result of the
Penning process of lithium atoms on noble gas atoms in the 1s states and subsequent ion-molecular reactions. Simultaneous radiation
at transitions of atoms of noble gases and lithium, heteronuclear ion molecules of noble gases allows us to increase the efficiency of
direct conversion of nuclear energy into light
