Laser spectroscopy of radioactive atoms using the photon-burst technique
The photon-burst technique has been used to perform laser spectroscopy on small samples of accelerator-produced radioactive isotopes. Measurements have been made of the isotope shifts in the resonance transitions of /sup 128/Ba (tau/sub 1/2/ = 2.4 days), /sup 126/Ba (tau/sub 1/2/ = 100 min), and /sup 82/Sr (tau/sub 1/2/ = 24 days). The technique has permitted high-resolution measurements to be performed in a few minutes on atomic beams of --100 atoms/sec of these elements. The laser-spectroscopy measurements of /sup 126/Ba are, to our knowledge, on the smallest samples of radioactive atoms (--10/sup 9/ atoms) used for high-resolution isotope-shift measurements performed to date. A technique is also demonstrated that, by producing a laser beam of spatially varying polarization, reduces optical pumping effects, allowing the photon-burst technique to be extended for use with odd isotopes as well as even.
