The frequencies of the hyperfine components of the transition
S
D3/2 in 107Ag and 109Ag have
been determined using Doppler-free two-photon laser spectroscopy
of a thermal atomic beam and heterodyne calibration with respect
to a molecular iodine line 111R(18-1) near 520 THz. For the
centre of gravity of a mixture of natural abundance, we deduce the
value 1 040 706 327(3) MHz. For the isotope shift, we obtain
MHz. We find the
magnetic hyperfine splitting constants of the excited state to be
A(107Ag (2D
MHz and
A(109Ag (2D
MHz, an order of
magnitude improvement over previous authors [W. Fischer et al., Z.
Phys. 238, 249 (1970)].
