Internal bremsstrahlung spectra of ߯ decaying nuclei for forbidden transitions obtaining by monte carlo

Work on internal bremsstrahlung (IB) has been going on for many years, although it has become very rare lately. Many theories have been performed in order to explain the mechanism of emission of the IB spectrum accompanying beta decay of nuclei. The original KUB theory has been found to be in disagreement with experiment in the intermediate and high-energy region. However, many of the differences observed between the theory and the experiments could not be explained until recently. The IB is a low-intensity continuous spectrum of electromagnetic radiation which accompanies all types of beta decay. Former experimental studies on the internal bremsstrahlung emission from the forbidden beta transitions have shown marked deviations from the theoretical calculations. We took the more theoretical calculations way for the IB probability. Calculations have been carried out from the work by Chang and Falkoff in which they proposed new analytic formulas for the IB spectrum for forbidden transitions. Also we have calculated the Coulomb effects of internal bremsstrahlung spectra from the Lewis and Ford who first addressed to this phenomenon. The analytical formulas for Coulomb effects are calculated from the expressions which are given in their study. We have handled and analyzed the data of IB emissions from different beta emitting isotopes such as(_15^32)P, (_37^86)Rb, (_38^89)Sr, (_38^90)Sr, (_39^90)Y, (_43^99)Tc, (_69^170)Tm and (_74^185)W. All of these isotopes are located in the forbidden energy zone except for (_15^32)P. We have proposed Monte Carlo calculation method which is developed by us for deriving IB spectra from the above isotopes. IB spectra from the analytical calculation results were compared that of our Monte Carlo calculation results.
