Limits on anomalous short-range spin-dependent interactions from spin-exchange collisions

ORAL

Abstract

Spin-exchange between light alkali atoms and noble gases proceed mainly due to the Fermi contact interaction in binary collisions, leading to small spin-exchange cross sections ($\sim $10$^{-24}$ cm$^{2})$. We investigate constraints on short-range ($\sim $1 nm) anomalous spin-dependent forces between nuclei based on the agreement between theoretical predictions and experimental measurements of spin-exchange cross sections for collisions between light alkali atoms and noble gases.
