Abstract
The spectrum shapes and circular polarization degree for the allowed and 1st forbidden internal bremsstrahlung (IBS) are investigated. Differences between the allowed and forbidden IBS are discussed. It is shown that the spectrum shapes and circular polarisation degree depend substantially on the beta-transition energyE 0.
