Abstract： Cs atoms were optically pumped with a Ti:sapphire laser in a magnetic field of 1.516T. Steady absorption spectra and populations of Zeeman sublevels of the ground state of Cs in N2 gas at various pressures (5, 40, and 80 Torr) were obtained. The results show that in a high magnetic field, the combined electron-nuclear spin transition (flip-flop transition), which is mainly induced by the collision modification δa( J . I ) of hyperfine interaction, is an important relaxation mechanism at high buffer-gas pressures.
