Using our previous approach to electromagnetic emission during tunneling, an explicit, essentially classical, formula describing the bremsstrahlung spectrum in alpha decay is derived. The role of tunneling motion in photon emission is discussed. The shape of the spectrum is a universal function of the ratio Eg/Eo , where Eg is the photon energy and Eo is a characteristic energy depending only on the nuclear charge and the energy of the alpha particle. 
Polarization bremsstrahlung in α decay
A mechanism of formation of electromagnetic radiation that accompanies α decay and is associated with the emission of photons by electrons of atomic shells due to the scattering of α particles by
Angular analysis of bremsstrahlung in α-decay
Abstract.A new quantum electrodynamical method of calculations of bremsstrahlung spectra in the α-decay of heavy nuclei taking into account the angle between the directions of α-particle motion (or
Emission of electromagnetic radiation in α-decay
The electromagnetic radiation during the non-uniform motion of the fragments resulting from the α-decay of a heavy nucleus is computed in a time-dependent quantum formalism. The dynamical
