Abstract

We calculate, including many-body effects, that the three lowest bound states of

{Mg}^{-}

,

2 p^{6} 3 s 3 p^{2} {}^{4}P

,

2 p^{6} 3 p^{3} {}^{4}S^{0}

and

2 p^{5} 3 s 3 p^{3} {}^{6}P

, have electron affinities 0.360, 0.514, and 1.321 eV, respectively. The transition

3 s 3 p^{2} {}^{4}P \to 3 p^{3} {}^{4}S^{0}

is found to have an electric dipole oscillator strength of 0.295. The lifetimes of the

J = \frac{1}{2}, \frac{3}{2}, and \frac{5}{2}

,

{}^{4}P

levels are estimated to be 7.8, 9.8, and 1.6 ns, respectively.
