X-RAY-EMISSION DURING THE MUONIC CASCADE IN HYDROGEN

We report our investigations of x rays emitted during the muonic casca de in hydrogen employing charge coupled devices as x-ray detectors. Th e density dependence of the relative x-ray yields for the muonic hydro gen lines (K-alpha, K-beta, and K-gamma) has been measured at densitie s between 0.001 15 and 0.97 of liquid hydrogen density. In this densit y region collisional processes dominate the cascade down to low energy levels. A comparison with recent calculations is given in order to de monstrate the influence of Coulomb deexcitation.
