    "abstract": "A quantum mechanical model for the description of the alpha-decay of heavy\nnuclei with accompanying photons emission is presented. The model is based on a\nquantum mechanical one-particle model of alpha-decay through a decay barrier.\nThe bremsstrahlung spectrum calculation employs multipole expansion of the\nvector potential of the Coulomb field of the daughter nucleus and takes into\naccount the dependence on the angle between the directions of the\nalpha-particle propagation and the photon emission. Spectra of 210Po are\nobtained for the angles 25 and 90, and the best agreement with the experimental\ndata in the 90 case in a comparison with other existing models is achieved.\n  From the angular analysis, the model gives monotonic behavior of the\nbremsstrahlung spectrum for any value of the angle. We find that sub-barrier\nphoton emission (i. e. bremsstrahlung photon emission during alpha-particle\ntunneling through decay barrier) exists but gives a small contribution to the\ntotal bremsstrahlung spectrum.",
