摘要	The parity violation effects via the 5d6s D-3(1) -> 6s(2) S-1(0) transition have been extensively investigated in ytterbium atoms. However, the M1 transition between the excitation state 5d6s D-3(1) and the ground state 6s(2) S-1(0), as well as the hyperfine-induced E2 transition, significantly affects the detection of parity violation signal. Therefore, it is imperative to obtain the accurate transition probabilities for the M1 and hyperfine-induced E2 transitions between the excitation state 5d6s D-3(1) and the ground state 6s(2) S-1(0). In this work, we use the multi-configuration Dirac-Hartree-Fock theory to precisely calculate the transition probabilities for the 5d6s D-3(1) -> 6s(2) S-1(0) M1 and hyperfine-induced 5d6s D-3(1,3) -> 6s(2) S-1(0) E2 transitions. We extensively analyze the influences of electronic correlation effects on the transition probabilities according to our calculations. Furthermore, we analyze the influences of different perturbing states and various hyperfine interactions on the transition probabilities. The calculated hyperfine constants of the e D-3(1,2,3) and D-1(2) states accord well with experimental measurements, validating the rationality of our computational model. By combining experimentally measured hyperfine constants with the theoretically derived electric field gradient of the extra nuclear electrons at the nucleus, we reevaluate the nuclear quadrupole moment of the Yb-173 nucleus as Q = 2.89(5) b, showing that our result is in excellent agreement with the presently recommended value.
