Abstract
Our recent experimental work on electron spin waves in atomic hydrogen gas has prompted a revisit of the theory of the identical spin rotation effect (ISRE). A key characteristic determining the properties of the spin waves is the quality factor of ISRE. Unfortunately, calculating this quality factor takes some toil. In this paper we summarize some results of the ISRE theory in dilute gases. We also derive asymptotic formulae for the quality factor and examine their accuracy for hydrogen and He-3.
