Gravitation and vacuum field

Equations that describe particles with spins s = 0, 1/2, 1 completely, i.e., also describe 2s + 2 limiting fields as E goes to infinity, are proposed. It is shown that the ordinary Hilbert-Einstein action for the gravitational field must be augmented by the action for the Bose vacuum field. This means that one must introduce in the gravitational equations a cosmological term proportional to the square of the strength of the Bose vacuum field. It is shown that the theory of gravitation decribes three realities: matter, field, and vacuum field. A new form of matter - the vacuum field - is introduced into field theory.
