This is the second of a series of papers on the radiative corrections oforder $\alpha^2 (Z\alpha)$, $\alpha (Z\alpha )^2$, and various logarithmicterms of order $\alpha^4$, to the hyperfine structure of the muonium groundstate. This paper deals with the $\alpha (Z\alpha)^2$ correction. Based on theNRQED bound state theory, we isolated the term of order $\alpha(Z\alpha)^2$exactly. Our result $+16.904 2 (11) \alpha(Z\alpha)^2 E_F / \pi$ for thenon-logarithmic part is consistent with the $\alpha (Z\alpha )^2$ part ofSapirstein's calculation and the recent result of Pachucki, and reduces thenumerical uncertainty in the $\alpha (Z\alpha)^2$ term by two orders ofmagnitude.Comment: 52 pages, RevTex and epsf.tex, 10 figures.
