Shivaramu,

External bremsstrahlung spectra produced by the complete absorption of ..beta.. particles from the decay of /sup 90/Sr, /sup 90/Y, and /sup 204/Tl in thick targets of Cu, Cd, Ta, and Pb are measured using a NaI(Tl) detector. The photon and energy yields and energy-yield constant are calculated using the unfolded bremsstrahlung spectra. The experimental data are compared with the numerical calculations based on the formulation of Pratt and his collaborators and the Born approximation theory of Bethe and Heitler. The experimental data agree with the Elwert-corrected Bethe-Heitler theory within experimental uncertainties for Cu and Cd, and a systematic positive deviation is found for Ta and Pb. The experimental data show good agreement with the numerical screened calculations of Pratt and his collaborators. The energy-yield constant is found to exhibit an energy dependence.
