The spin Hamiltonian that describes the molecular magnet Fe8has biaxial symmetry with mutually perpendicular easy, medium, and hard magnetic axes. Previous calculations of the ground-state tunnel splittings in the presence of a magnetic field along the hard axis are extended, and the meaning of the previously discovered oscillation of this splitting is further clarified.
