Internal Conversion inSn119

The total internal conversion coefficient of the ground-state 23.8-keV transition in ${\mathrm{Sn}}^{119}$ and the ratio ${\left[\frac{K}{(L+M+\cdots )}\right]}_{M4\mathrm{}}$ of internal conversion coefficients of the preceding 65.3-keV $M4\mathrm{}$ transition have been determined by measuring the coincidence rate between the $K$ x rays following internal conversion of the 65.3-keV transition, and the 23.8-keV gamma rays. The following results were obtained: $\alpha =5.2\mathrm{}\pm 0.3$ and ${\left[\frac{K}{(L+M+\cdots )}\right]}_{M4\mathrm{}}=0.42\mathrm{}\pm 0.02$.
