Hyperfine Structure of the MetastableP23State ofCd111andCd113

Abstract

The hyperfine intervals of ${\mathrm{Cd}}^{111}$ and ${\mathrm{Cd}}^{113}$ ($5s, 5p, {}_{}{}^3{}_{}{}^{}P_2^{}{}_{}{}^{}$) are $\Delta {\nu }^{111}(F=\frac{5}{2}, F=\frac{3}{2})=(8232.341\mathrm{}\pm 0.002)$ Mc/sec; $\Delta {\nu }^{113}(F=\frac{5}{2}, F=\frac{3}{2})=(8611.586\mathrm{}\pm 0.004)$ Mc/sec. The measured hyperfine anomaly is (0.0016±0.0003)%.
