A new measurement of the g/subJ/ factor in the 2$sup 3$$S$$sub 1$ metastable state of $sup 4$He has been made using an optical-pumping technique. Our result is g/subJ/($sup 4$He,2$sup 3$$S$$sub 1$)/g/subJ/($sup 1$H,1$sup 2$$S$$sub 1$$/$$sub 2$) =1--23.15(10) x10$sup -6$. This value agrees with theory and provides confirmation of a recent atomic-beam measurement. Further doubt is cast on an earlier optical-pumping determination, thereby resolving a possible discrepancy between theory and experiment. (AIP)
