  We investigate the decay of an arbitrary neutral boson into a pair of
on-shell W-bosons in a magnetic field. The possible existence of the new
neutral bosons with the spins 0, 2, 3 and with the charge conjugation C=+1 in
the energy (mass) range from zero to 160.77 GeV is predicted. The analyses show
that the existence of the neutral boson with the spin 2 in the energy (mass)
range from zero to 160.77 GeV is more promising and realistic.
