The applicability of the single-electron model in describing the electron detachment of the hydrogen negative ion in strong (static or laser) fields is examined. By comparing the values for the lowest state energies and detachment rates obtained using two different short-range model-potentials with the results of recent ab initio calculations using the full two-electron description (Milosevic and Simonovic, 2016), it is found that the single-electron description is applicable for the field intensities up to few hundred GW/cm2. This description, therefore, can be used for studying multiphoton processes or the electron detachment via tunneling at these field strengths, but fails in over-the-barrier regime.

Short Range Correlations

Pairing properties of infinite matter are surveyed that are obtained from self-consistent Green's function calculations. A complete treatment of off-shell propagation that incorporates the effects of short-range correlations is included. Mean-field calculations based on the BCS approach are superseded by the present results, which resolve a long-standing puzzle associated with 3S1-3D1 (proton-neutron) pairing in symmetric nuclear matter. Results for 1S0 pairing in pure neutron matter are in agreement with recent Monte-Carlo calculations for this system. The possibility of proton pairing in finite nuclei, as a result of increasing proton correlations with increasing nucleon asymmetry, is pointed out.
