Measurement of the Angular Correlation Coefficient in Neutron Decay.
Abstract
The document is a continuation of the work started under Contract 61(052)-857. The aim is to determine the angular correlation constant, and hence, the coupling constant ratio C sub A/C sub V, in neutron beta decay by measuring the shape of the proton recoil spectrum. Further preliminary investigations were done concerning the effect of neutron motion and finite spectrometer resolution upon the spectrum, on the optimization of the measurement cycle, and on the appearance of surface charges under electron irradiation. The beam tube insert and the vacuum system have been assembled and tested. The magnetic shielding inside the beam tube was tested. The proton test source has been finished. The proton detector has been tested, and it was possible to reduce the background counting rate to a sufficiently low value. The control and data output system has been finished and tested. An evaluation of coupling constants in beta decay using published data was done by means of a computer program. (Author)
