The Measurement of Lande g Factor of ³D₁ with Cold ⁸⁸Sr Atoms

We experimentally observed the resolved Zeeman spectroscopy of the P-3(0)-D-3(1) transition using the cold Sr-88 atoms, and measured the Lande g factor of D-3(1) on the basis of the observable spectroscopy under different magnetic fields, which indicates the measured value is 0.4997(91) in good agreement with the calculated value of 0.4988. The detailed experimental scheme is presented here. Benefitting from the scheme, Sr atoms can be trapped in a mageto-optical trap (MOT) at a low temperature and a high density. The measurement of g(J) of D-3(1) is beneficial to investigate the long range dipolar interaction on the P-3(0)-D-3(1) transition of Sr-88.
