Dynamics of thermoluminescence spectra of impurity– helium condensates containing stabilized nitrogen and oxygen atoms

Dynamics of thermoluminescence spectra of impurity– helium condensates containing stabilized nitrogen and oxygen atoms

The results of investigations of thermoluminescence dynamics during destruction of neon–helium and krypton–helium condensates containing stabilized nitrogen and oxygen atoms are presented. Spectra of the thermoluminescence of a krypton–helium condensate contained bands of N and O atoms and NO mole...
