Photodetachment of H⁻ near a hard wall with arbitrary laser polarization direction

Iqbal Azmat†^a), Afaq A.^b)

Dependences of photodetachment cross section given in Eq. ( 20 ) on laser polarization direction θ _L for a fixed source–wall distance d = 200 a.u. The amplitude of oscillation is maximum when the laser polarization direction is along the z axis, i.e., perpendicular to the wall at θ _L = 0 as represented by the dashed oscillatory curve. Oscillation in cross section vanishes at θ _L = π /2 when the laser polarization direction is parallel to the wall as represented by the smooth thick curve. At θ _L = π /4, the amplitude of oscillation is half of the maximum and minimum values at θ _L = 0, and θ _L = π /2 respectively.
