  There are constructed exact solutions of the quantum-mechanical equation for
a spin S=1 particle in 2-dimensional Riemannian space of constant negative
curvature, hyperbolic plane, in presence of an external magnetic field,
analogue of the homogeneous magnetic field in the Minkowski space. A
generalized formula for energy levels describing quantization of the motion of
the vector particle in magnetic field on the 2-dimensional space H_{2} has been
found, nonrelativistic and relativistic equations have been solved.
