Finite nuclear size and radiative corrections in the construction and assessment of kurie plots for allowed beta-decay

Abstract

If only a small fraction of a beta-spectrum is available for Kurie plot analysis because of the existence of strong branches of lower energy, it may become important to take into account finite nuclear size and radiative effects in the construction and assessment of the Kurie plot. Failure to do this may result in errors of many percent in the extraction of the intensity of the high energy beta-branch. These effects are analyzed and numerical estimates are made of the possible errors.
