Cheng, Yongjun Mitroy, J Absorption oscillator strengths for some low-lying transitions of Ga<sup>2 +</sup> <p><b>Table 2.</b> Absorption oscillator strengths for some low-lying transitions of Ga<sup>2 +</sup>. The acronyms MP and RCC are defined in the text while RMBPT refers to relativistic many body perturbation theory and MCHF refers to (non-relativistic) multi-configuration Hartree–Fock.</p> <p><strong>Abstract</strong></p> <p>The blackbody radiation shift of the Ga<sup>+</sup>4{\rm s}^2 \ ^1{\rm S}^{\rm e}_0 \rightarrow 4{\rm s}4{\rm p} \ ^3{\rm P}^{\rm o}_0 clock transition is computed to be −0.0140 ± 0.0062 Hz at 300 K. The small shift is consistent with the blackbody radiation shifts of the clock transitions of other group III ions which are of a similar size. The polarizabilities of the Ga<sup>+</sup>4{\rm s}^2 \ ^1{\rm S}^{\rm e}_0, 4{\rm s}4{\rm p} \ ^3{\rm P}^{\rm o}_0, and 4{\rm s}4{\rm p} \ ^1{\rm P}^{\rm o}_1 states were computed using the configuration interaction method with an underlying semi-empirical core potential. Quadrupole and non-adiabatic dipole polarizabilities were also computed. A byproduct of the analysis involved calculations of the low-lying spectrum and oscillator strengths, including polarizabilities, of the Ga<sup>2 +</sup> ion.</p> rmbpt;body perturbation theory;blackbody radiation shift;acronyms MP;clock transitions;MCHF;blackbody radiation shifts;oscillator strengths;polarizabilitie;configuration interaction method;rm;Ga 2;group III ions;rcc;Atomic Physics;Molecular Physics 2013-09-06
