The transitions between the 2S and 2P states of the muonic helium atom (..cap alpha mu.. or /sup 3/He-..mu..) in collisions with hydrogen atoms are examined using the rectilinear-trajectory coupled-equation method. The 2S level shift is included semiempirically and the target atom is approximated using the frozen ground-state charge density. Partial decoupling of the coupled equations is achieved, and some simple approximations for the 2S-to-2P transition probability are derived and compared with the exact solution of the coupled equations. The cross section obtained is fit by sigma/sub 2//sub S//sub -//sub 2//sub P/approx. =5.5 x 10/sup -3// v/sup 1.8/a/sub 0//sup 2/ for vapprox. >1, with the velocity v in atomic units, and muon-catalyzed fusion parameters are reevaluated using this expression.
