Abstract

Doppler-free isotope shift measurements of the stable even 184–192Os and 187,189Os odd isotopes have been performed for the first time on the 5d 66s 2 5D4→5d 66s6p 7F4 (305.9 nm) transition in the neutral atom by atomic beam laser spectroscopy and on the ionic 5d 66s 5D9/2→5d 66p 6D7/2 (228.2 nm) transition by fast collinear ion-laser spectroscopy. The measurements were carried out in Manchester and at the IGISOL facility in Jyväskylä in Finland, respectively. The results presented are the most precise measurements to-date of the absolute isotope shifts.
