Abstract

We report an electron-beam study of dissociative attachment from excited hydrogen in the energy range of 1-5 eV. A marked dependence of

H^{-}

/

H_{2}

and

D^{-}

/

D_{2}

cross sections on initial vibrational (

v = 0 - 5

) and rotational (

j = 0 - 7

) states is observed. These results provide a new mechanism to interpret the anomalous

H^{-}

density recently observed in a hydrogen plasma.
