  We investigate possibility of emission of the bremsstrahlung photons in
nuclear reactions with hypernuclei for the first time. A new model of the
bremsstrahlung emission which accompanies interactions between $\alpha$
particles and hypernuclei is constructed, where a new formalism for the
magnetic momenta of nucleons and hyperon inside hypernucleus is added. For
first calculations, we choose $\alpha$ decay of the normal nucleus $^{210}{\rm
Po}$ and the hypernucleus $^{211}_{\Lambda}{\rm Po}$. We find that (1) emission
for the hypernucleus $^{211}_{\Lambda}{\rm Po}$ is larger than for normal
nucleus $^{210}{\rm Po}$, (2) difference between these spectra is small. We
propose a way how to find hypernuclei, where role of hyperon is the most
essential in emission of bremsstrahlung photons during $\alpha$ decay. As
demonstration of such a property, we show that the spectra for the hypernuclei
$^{107}_{\Lambda}{\rm Te}$ and $^{109}_{\Lambda}{\rm Te}$ are essentially
larger than the spectra for the normal nuclei $^{106}{\rm Te}$ and $^{108}{\rm
Te}$. Such a difference is explained by additional contribution of emission to
the full bremsstrahlung, which is formed by magnetic moment of hyperon inside
hypernucleus. The bremsstrahlung emission formed by such a mechanism, is of the
magnetic type. A new formula for fast estimations of bremsstrahlung spectra for
even-even hypernuclei is proposed, where role of magnetic moment of hyperon of
hypernucleus in formation of the bremsstrahlung emission is shown explicitly.
Such an analysis opens possibility of new experimental study of properties of
hypernuclei via bremsstrahlung study.
