Abstract
A high-statistics measurement of bremsstrahlung emitted in the α decay of 210Po has been performed. The measured differential emission probabilities, which could be followed up to γ-energies of ∼ 500 keV, allow for the first time for a serious test of various model calculations of the bremsstrahlung accompanied α decay. It is shown that corrections to the α-γ angular correlation due to the interference between the electric dipole and quadrupole amplitudes and due to the relativistic character of the process have to be taken into account. With the experimentally derived angular correlation the measured energydifferential bremsstrahlung emission probabilities show excellent agreement with the fully quantum mechanical calculation.
