Zeeman shifts in one of the J=2 order-parameter collective-mode multiplets in He3-B have been measured in magnetic fields up to 0.16 T. The observed shifts are extremely nonlinear at higher fields. The extent of nonlinearity decreases as TTc0 and for a given TTc is more predominant at lower pressures and/or frequencies. The observed effects can be attributed to the distortion of the B-phase energy gap in the presence of a magnetic field as suggested by Schopohl, Warnke, and Tcwordt.
