Abstract

Doppler-free two-photon spectroscopy was applied to excite hyperfine-induced transitions from the

5 s^{2} {}^{1}S_{0}

ground state to the

F = I

component of the hyperfine multiplet of the

5 s n s {}^{3}S_{1}

Rydberg series of

{}^{87}{Sr}

(

n = 50, \dots, 85

). The experimental data confirm the interpretation of hyperfine-induced singlet-triplet mixing which is related to the singlet-triplet energy separation.
