What is the difference in the p-wave and s-wave photodetachment in an electric field?

TL;DR

This paper derives a simple formula for s-wave photodetachment modulation in an electric field, compares it with p-wave behavior, and analyzes how their oscillation patterns differ based on laser polarization angles.

Contribution

It introduces a new formula for s-wave modulation function and compares its phase and amplitude characteristics with p-wave modulation in an electric field.

Findings

Maximums in s-wave correspond to minimums in p-wave due to phase difference.

Oscillation amplitudes vary with the angle between laser polarization and electric field.

The phase difference is approximately π, affecting the modulation patterns.

Abstract

By applying closed-orbit theory to an existing model, a simple formula is derived for the modulation function of s-wave photo-detachment in the presence of a static electric field. We then compare the s-wave modulation function with the p-wave modulation function. We show the maximums (minimums) in the s-wave modulation function correspond to the minimums (maximums) in the p-wave modulation function because of a phase difference of $\pi$ in their oscillations. The oscillation amplitude in the p-wave modulation function can be larger than, smaller than or equal to the oscillation amplitude of s-wave modulation function when the angle between the laser polarization direction and the static electric field direction is tuned to be smaller than, larger than or equal to a special angle which is approximately $54.74^\circ$.
