W. Huttner et al., 2ND-ORDER ZEEMAN-EFFECT IN THE 5(2)S-3(2)S AND 4(2)D-3(2)S 2-PHOTON TRANSITIONS OF ATOMIC SODIUM, Physical review. A, 54(2), 1996, pp. 1318-1321
We have observed the second-order, field-induced Zeeman effects of the
Doppler-free two-photon transitions 5 S-2-3(2)S and 4 D-2-3(2)S of at
omic sodium using fields up to 5 T. Using a suitable experimental conf
iguration it was possible to avoid the appearance of first-order effec
ts in the high-field limit. The remaining small field-induced shifts a
re of the order of magnitude of a few linewidths. They yield the diffe
rences of the diamagnetic susceptibilities of the connected atomic sta
tes. The method is therefore capable of providing data related to atom
ic electronic structure.
