Antiparticles of spin s were identified with negative energy particle solutions of spin s, instead of�s. Incorporating thischange, � in Eqs. (12), (13), (14), and (23) should be replaced by �, and � in Eq. (22) should be replaced by �. Ourresults now agree with Ref. [3]. Our earlier results agreed with Refs. [2] and [4] which perhaps contain the samemisinterpretation. The overall minus sign in the expectation value of the evenized velocity and force for antiparticles can beabsorbed by taking the expectation value of the momentum in antiparticle states to be �pz, as for systems with constantmass, where the energy eigenstates are also momentum eigenstates.
