Abstract

The spin-forbidden optical transitions of

{Co}^{2 +}

{Ni}^{2 +}

, and

{Mn}^{2 +}

have been observed in doped crystals of Mg

F_{2}

following both

γ

and electron irradiation. Radiation-induced

F

centers trapped at impurity sites appear to reduce the forbiddenness significantly for many of the transitions. Oscillator strength increases of up to

10^{3}

have been recorded.
