Relative Intensities ofKandLSeries of Muonic X Rays

Relative intensities of muonic x rays have been measured for the $K$ series of Ca, S, Si, and Mg and $L$ series of Ca. $K_{\alpha }$ yields of all the elements are about 80% of the total $K$ lines. The relative intensities of Ca $K_{\gamma }$, $K_{\delta }$, $K_{\epsilon }$, and $K_{\zeta }$ x rays are almost constant and are about 2% of the total $K$ lines. A statistical initial distribution of muons in a high-$n$ state might be sufficient to explain the data if electron stripping effects are included in the calculations.
