Hamiltonian form of the Kemmer equation for spinless boson

Abstract

It is shown that for a free spinless particle described by the Kemmer equation, the Hamiltonian which Kemmer originally presented yields a velocity operator whose expectation value does not agree with the correspondence principle. Hamiltoniaos for a free spinless particle and a spinless particle in an electromagnetic field are constructed from the Kemmer equation. These Hairoi I toniaos differ from the ones originally presented by Kemmer. The free particle Hamiltonian yields a velocity operator whose expectation value is consistent with the correspondence principle.
