RECOIL ENERGY SPECTRUM OF THE SODIUM IONS FOLLOWING THE /cap beta/$sup -$ DECAY OF Ne$sup 2$$sup 3$

Following the beta decay of Ne/sup 23/, the sodium ions have a recoil energy distribution which is dependent on the nature of the decay. A precise measurement was made of the recoil spectrum from 100 to 500 ev. From these data the electron-neutrino angular correlation coefficient alpha was determined to be --0.33 plus or minus 0.03, in good agreement with V-A interaction. The quoted error includes an uncertainty of only 2% due solely to the recoil measurements. The principal uncertainty in alpha arises from the errors quoted by Penning andd Schmidt for their measurements of the BETA --ray intensities to the ground and first excited states. If it is assumed that V-A interaction is valid andd hence alpha = 1/3, the BETA /sup -/-ray intensities to the ground and first excited states of Na/sup 23/ may be calculated from the recoil data. Such calculations were made and the results are, respectively, (67 plus or minus 1)% and (32 plus or minus 1)%. From the end point of the recoil spectrum, the decay energy to the ground state was determined to be 4.383 plus or minus 0.008 Mev. (auth)
