  This paper is a prosecution of a previous work where we presented a unified
two-fermion covariant scheme which produced very precise results for the masses
of light and heavy mesons. We extend the analysis to some radiative decays of
mesons $\Upsilon,\,\chi_{b2}\,,h_b\,,\chi_{b1}\,,\chi_{b0}\,,\eta_b\,$ and we
calculate their branching ratios and their widths. For most of them we can make
a comparison with experimental data finding a good agreement.For the decays for
which data are not available we compare ours with other recent theoretical
previsions.
