Spectral and temporal behavior of resonant secondary emission in NaNO2
has been investigated over the temperature range 2-20 K. Typical valu
es of tau(c) and Gamma are derived from the fitting analysis of the ob
served ratio (I-L + I-R(slow))/I-total at 2 and 8 K. The value of Gamm
a is found to increase by a factor 5 for the temperature change from 2
to 8 K.
