Study of inner bremsstrahlung accompanying beta decay in¹⁸⁵W and⁹⁰Y

Abstract

Inner bremsstrahlung spectra of 185W and 90Y are studied using the magnetic deflection technique. The experimental spectrum of 185W was unfolded using the detector response matrix. The results show good agreement with the Coulomb corrected theory of R.R. Lewis, Jr. and G.W. Ford (1956). The procedure of K. Liden and N. Starfelt (1955) was used to unfold the experimental spectrum of 90Y. The results show reasonable agreement with the detour theory of G.W. Ford and C.F. Martin (1969). The intensity of the IB spectra shows an increasing trend towards the end-point energy of the beta ray.
