Abstract

Singlet-triplet mixing of

4 s n d {}^{1}D_{2}

and

{}^{3}D_{2}

states of Ca was determined between principal quantum numbers

7 <~ n <~ 42

with the use of Doppler-free two-photon spectroscopy. The hyperfine structure of the

4 s n d {}^{1}D_{2}

states was used to probe admixtures of triplet character into the singlet wave functions. It turned out that, in the region of series crossings, an enlarged singlet-triplet mixing was observed.
