Abstract
The initial sticking in the states of muonic helium in muon-catalyzed fusion () and the subsequent collisional excitation to these states are shown to have nonstatistical dependences on that result in spatial anisotropy of the emitted x rays. This anisotropy, , is found to be 0.71 for and 1.12 for in liquid targets, where the angle is between the coincidently detected x ray and neutron. The effect is predicted to increase the actual x-ray yield and corresponding sticking observed in a recent experiment by 4%. The Doppler broadening of the radiation observed at different angles is also examined.
