Unusual spin-precession states of 3He-B in which the magnetization is half the equilibrium value are investigated by continuous-wave NMR methods. Signals at
frequencies equal to 1/2 and 3/2 of the magnetization precession frequency are observed in two such states. Such signals exist
because the order parameter of superfluid 3He in these states precesses with frequency equal to half the magnetization precession frequency.
