  The Proca-Corben-Schwinger equations for a spin-1 particle with an anomalous
magnetic moment are added by a term describing an electric dipole moment, then
they are reduced to a Hamiltonian form, and finally they are brought to the
Foldy-Wouthuysen representation. Relativistic equations of motion are derived.
The needed agreement between quantum-mechanical and classical relativistic
equations of motion is proved. The scalar and tensor electric and magnetic
polarizabilities of pointlike spin-1 particles (W bosons) are calculated for
the first time.
