Bound-free transitions in H + H ^– collisions

Abstract

Abstract. The processes of photo-detachment or ionization of stable molecules are widely investigated in modern atomic physics. But the present work deals with the calculation of the photo-detachment cross-sections in the case of negative quasi-molecules formed during collisions. The reaction H + H − +hω → H + H + e has been taken as an example of bound-free transitions in single-active-electron quasi-molecules. For simplicity, we discuss the one-dimensional case in the frame of the zero-range potential model.

Eigenfunctions of continuous spectrum in the problem of the two zero range potentials

“…For example, in (Lapidus 1970), such a model in a one-dimensional version is used to describe a positive molecular hydrogen ion. In (Devdariani, Dadonova 2015;2018;Devdariani et al 2014;2017), the model is used to describe collisions of hydrogen atoms with a negative hydrogen atomic ion, which is much more realistic than using it to describe…”
