Hyperfine structure and isotope shift of highly excited barium-I states

In English

Författare

Summary, in English

High-resolution laser-spectroscopy measurements of hyperfine structure and isotope shifts were performed for the 6snd 1 D 2 sequence of Ba-I in the regionn=12–24. Stepwise laser excitations of a collimated atomic beam were used. A strong influence on the hyperfine structure is observed at the perturbation atn=14, caused by interaction with the 5d7d configuration. Whereas the isotope shift for the even isotopes stays essentially constant with increasingn, the odd isotopes exhibit a strong change, indicating hyperfine-induced shifts.

Interesting discussions with Prof. E. Matthias in the final stage of this work are gratefully acknowledged. This work was supported by the Swedish Natural Science Research Council.
