Hyperfine structure and radiative-lifetime determination for the 4d106p2Pstates of neutral silver using pulsed laser spectroscopy

The hyperfine structure and radiative lifetime of the 4${\mathit{d}}^{10}$6p ${}_{}{}^2{}_{}{}^{}$P states of neutral silver were determined in pulsed level-crossing, optical-double-resonance, and time-resolved experiments using high-power frequency-tripled radiation from a dye laser. For the ${}_{}{}^2{}_{}{}^{}$ ${\mathit{P}}_{3/2}$ state, we obtained τ=78(5) ns for the lifetime and ‖a‖=9.05(25) MHz for the magnetic-dipole interaction constant of ${}_{}{}^{107}{}_{}{}^{}\mathrm{Ag}$. The lifetime and the a factor for the ${}_{}{}^2{}_{}{}^{}$ ${\mathit{P}}_{1/2}$ state were determined to be τ=95(6) ns and ‖a‖=38.7(10) MHz, respectively, using time-resolved laser spectroscopy. The experimental results are compared with theoretical calculations using the multiconfiguration Hartree-Fock method.
