Abstract
It is shown that below the threshold of pair creation, a consistent quantum mechanical interpretation of relativistic spin0 and spin1 particles (both massive and massless) is possible based on the HamiltonianSchrodinger form of the firstorder Kemmer equation together with a firstclass constraint. The crucial element is the identification of aconserved fourvector current associated with the equation of motion,whose time component is proportional to the energy density which is constrained to be positive definite for all solutions. Consequently, the antiparticles must be interpreted as positiveenergy states traveling backward in time. This also makes it possible to define hermitian position operators with localized eigensolutions (deltafunctions) as well as Bohmian trajectories for bosons. The exact theory is obtained by''second quantization'' and is mathematically completely equivalent to conventional quantum field theory. The classical field emerges in the high mean number limit of coherent states of the exact theory. The formalism provides a new basis for computing tunneling times for photons and chaotic phenomena in optics.
