TL;DR
This paper investigates how long-range forces influence cold-atomic interactions in the Ps-H system, revealing a Feshbach resonance at ultra-low energy levels through a modified static-exchange model.
Contribution
It introduces a modified static-exchange model to analyze long-range effects and reports a novel Feshbach resonance in the Ps-H system at very low energy.
Findings
Identification of a Feshbach resonance at ~3x10^{-6} eV
Analysis of s-wave elastic phase-shifts and cross sections
Evidence of long-range force effects in cold-atomic interactions
Abstract
The s-wave elastic phase-shifts and s-wave elastic cross sections are studied to find the effect of long-range forces on cold-atomic interactions using a modified static-exchange model for Ps-H system. A Feshbach resonance in the triplet channel using the modified static-exchange model at the energy ~ 3x10^{-6} eV caused by long-range forces in the Ps-H system is being reported.
