Abstract

The ratio of the /spl gamma//sup 4/He//spl gamma//sup 3/He has been measured using a gaseous sample in the low magnetic field. The result is /spl gamma//sup 4/He//spl gamma//sup 3/He=864.02276(0.03 ppm), leads to a value of /spl gamma//sup 4/He=1760.78798(0.3 ppm)/spl middot/10/sup 8//spl middot/rad/spl middot/s/sup -1//spl middot/T/sup -1/ using 1990 recommended value of /spl gamma//sub p/´=2.6751542(8)/spl middot/10/sup 8//spl middot/rad/spl middot/s/sup -1//spl middot/T/sup -1/ and /spl gamma//sup 3/He//spl gamma//sub p/´=0.7617861313(33) of Flowers et al. (1993).
