Description:
We have detected absorption features in the far-ultraviolet spectrum of zeta Tau (B3pe), one of which corresponds to a new transition involving quasi-H/-/, and the other to a transition involving quasi-H2/+/. The former transition produces a broad absorption feature on the red wing of L-alpha. It is the result of the absorption of a photon by a ground-state hydrogen atom and colliding electron, and it leads to the excitation of both electrons to the 2p2 3Pe state of H/-/.
