Hyperfine Structure ofGe73in theP13andP23Atomic States and the Nuclear Magnetic Dipole Moment ofGe71

The hyperfine-structure constants of ${\mathrm{Ge}}^{73}$ in the ${}_{}{}^3{}_{}{}^{}P_1^{}{}_{}{}^{}$ and ${}_{}{}^3{}_{}{}^{}P_2^{}{}_{}{}^{}$ atomic states of the $3p^2$ electronic configuration have been measured with the atomic-beam magnetic-resonance method. The values of the magnetic dipole hyperfine-interaction constant $a$ are 15.5480(18) Mc/sec and -64.4270(7) Mc/sec, respectively, for the ${}_{}{}^3{}_{}{}^{}P_1^{}{}_{}{}^{}$ and ${}_{}{}^3{}_{}{}^{}P_2^{}{}_{}{}^{}$ states. The nuclear electric quadrupole interaction constants $b$ are -54.566(9) Mc/sec and +111.825(13) Mc/sec, respectively, for these two states. On the basis of these measurements of $a$, the known spin and nuclear magnetic dipole moment of ${\mathrm{Ge}}^{73}$ and the measured spin and $a$ factors of ${\mathrm{Ge}}^{71}$, the nuclear magnetic dipole moment of ${\mathrm{Ge}}^{71}$ can be calculated. It is $\mu =0.546\mathrm{}\left(5\right)\mathrm{}$ nm.
