The luminescence of Kr-Xe, Ar-Kr, and Ar-Xe mixtures was studied in the spectral range 300–970 nm when excited by ⁶Li (n, α)³ H 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. The 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. The 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.

6Li（n，α）3 H核反应产物激发下稀有气体二元混合物的排放

在⁶ Li（n，α）³激发下，在300-970 nm的光谱范围内研究了Kr-Xe，Ar-Kr和Ar-Xe混合物的发光H核反应产物位于核反应堆的核心。锂以毛细管-多孔结构形式沉积在实验电池的壁上，这使得可以测量高达730 K的温度。稀有气体原子，碱金属和异核离子辐射强度的温度依赖性研究了稀有气体分子。而且，如在单组分气体的情况下，锂线的出现以及钠和钾的杂质与从锂层释放核反应产物期间的汽化有关。锂原子的激发主要是由于锂原子在稀有气体原子上以1s态发生的Penning过程以及随后的离子分子反应而发生的。在稀有气体和锂原子的跃迁处同时辐射，
