We report the observation of the very narrow 4d{sup 10}5s {sup 2}S{sub 1/2}{yields}4d{sup 9}5s{sup 2} {sup 2}D{sub 5/2} transition in atomic silver. The frequencies of the hyperfine components in {sup 107}Ag and {sup 109}Ag have been measured using Doppler-free two-photon laser spectroscopy of a thermal beam and heterodyne calibration with respect to the a{sub 1} component of the 62P(4-5) line in molecular iodine near 661 nm. For the center of gravity of a mixture of natural abundance, we deduce the value 906 641 295.77(19) MHz. For the isotope shift, we obtain {nu}({sup 109}Ag)-{nu}({sup 107}Ag)=564.15(37) MHz, from which we deduce the frequency and isotope shift of the 4d{sup 10}5s {sup 2}S{sub 1/2}{yields}4d{sup 10}6p {sup 2}P{sub 3/2} transition at 206 nm.
