  We have determined that the decay of the neutral boson at a mass around 125
GeV into an on-shell W^-W^+-pair in a uniform magnetic field becomes, in
principle, possible and the new decay channel of this boson in a magnetic field
is allowed by the energy and total angular momentum conservation laws. The
required magnetic field strength for observation of the measurable effect is
~10^23 G (or in Teslas ~10^19 T). The existence of the other neutral boson with
the spin J=0 and with the other mass is not either excluded in the mass range
below 2m_W=160.77 GeV.
