Frequency measurement, isotope shift and hyperfine structure of the 4d95s2 2D5/2 → 4d106p 2P3/2 transition in atomic silver

The frequency of the centroid of the transition 4d(9)5s(2) D-2(5/2) --> 4d(10)6p P-2(3/2) in Ag I has been determined by laser spectroscopy of a collimated metastable thermal atomic beam. We find nu = 547 376 388(60) MHz. The isotope shift nu(Ag-109) - nu(Ag-107) = -982.6(5.4) MHz. For the magnetic hyperfine structure constant of the 4d(10)6p, P-2(3/2) state, assuming IJ coupling, we find, A(Ag-107) = -8.4(6) MHz and A(Ag-109) = -10.2(6) MHz.
