The initial sticking in the 2p/sub m/ states of muonic helium in muon-catalyzed fusion (..mu..CF) and the subsequent collisional excitation to these states are shown to have nonstatistical dependences on m that result in spatial anisotropy of the emitted x rays. This anisotropy, I(0/sup 0/)/I(90/sup 0/), is found to be 0.71 for d-d ..mu..CF and 1.12 for d-t ..mu..CF in liquid targets, where the angle is between the coincidentally detected x ray and neutron. The effect is predicted to increase the actual K..cap alpha.. x-ray yield and corresponding sticking observed in a recent d-t ..mu..CF experiment by 4%. The Doppler broadening of the radiation observed at different angles is also examined.
