The internal bremsstrahlung ofα-particles emmited byα-decaying nuclei is not responsible for the internal pair production inα-decay. The probability of this process is of the order of 10−20, in strong disagreement with previous resuls. It is suggested that the internal pair production inα-decay is due to excited states in nuclei. For the probability of this process a value of the order of 10−12 has been obtained.
