level-crossing effects have been detected non-optically with the use of a rabi-type atomic-beam method. the sodium beam was excited by intense linearly polarised radiation from a cw narrow-band dye laser. several superimposed resonances were observed in the atomic-beam signal when scanning the magnetic field around zero. the two narrower resonances are interpreted as high-order non-linear effects. they arise from the coupling of laser-induced zeeman coherences in the ground state (including a hexa-decapole moment) with the populations of the zeeman sublevels
