Abstract
A lot of narrow lines on R2, R+, N1, N- and some other unknown centers have been observed in gamma-rayed pure and doped sodium fluoride crys tals in the temperature range of 9-77K. The proper laser irradiation w as used for strengthening the zero-phonon lines and the relative expla nation was given. The spectral properties and thermostabilities of the lines were investigated systematically at different temperatures.
