Abstract

i0.010 Mev. Also, these plots are linear for energies greater than 0.6 Mev, but below this energy the points gradually rise above the straight line. This effect is observed even the continuous spectrum are 0.97040.010 Mev and 0.605 +0.014 Mev. The end point of the low energy component was obtained by subtracting the sum of the energies of the low intensity gamma-rays from the maximum energy of the high energy beta-component. From the position of the inflection point in the Kurie plot we obtained a value for the low energy end point that agrees with, but is less accurate than, the value given above. The intensity of the low energy component is 15 percent, or less. The uncertainty in this figure is difficult to estimate since, in determining it, we had to assume that the back-scattering and absorption in the thinnest source was negligible. A paper giving full details of this investigation and a discussion of the beta-ray theory involved is in preparation. I J, L. Lawson and J. M. Cork, Phys. Rev. 58, 580 (1940). 2 E. H. Plesset, Phys.
