Selfbroadening of Hanle signals arising from observation of the backscattered light has been studied with mercury vapor at pressures up to 1 torr. The theory of this broadening is developped ; it arises from resonant collisions between mercury atoms as well as by their collisions with the walls and by their penetration into the vapor. This motion effect may be responsible for up to 35 % of the total broadening ; it critically depends upon the frequency of the exciting radiation and upon the concentration of the isotope studied. The results of this theory together with the results of resonant collisions theory agree very well with the measurements of different Hanle signals observed for several profiles of the excitation line and for various...
