Study of low-energy internal Bremsstrahlung radiation from 147Pm

Abstract

The absolute intensity of the internal Bremsstrahlung radiation following the beta decay of 147 Pm has been measured using a high-resolution X-ray detector in the low-energy region from 3 to 33 keV. Magnetic-deflector method has been used to avoid the betas from reaching the detector. The corrected spectral intensity has been compared with the Nilsson-corrected KUB theory. Good agreement between experiment and theory is seen in this energy region. r
