Physica XIX 433-444 MEASUREMENTS ON THE CONTINUOUS BETA-SPECTRA, THE CONVERSION LINES AND THE AUGER-LINES OF U(X, +X2) by P. H. STOKER *), M. HEERSCHAP t) and ONG PING HOK 1. I&roductiolz.
In a previous paper ') measurements on the p-spectrum of U(X, + X,) with a thin mica-foil as source carrier and performed in a semi-circular spectrometer were described.
Since backscattering against the mica-foil distorted the low energy region of the spectrum, we now used a thin film of plastic material ") and remeasured the spectrum not only in the semi-circular but also in a 16.2 cm double-focusing spectrometer ") at a resolution of 1.5 Oh. A classification of the electron lines found, as internal conversion and Auger lines is given in section 4. After a Fermi-Kurie analysis (section 5) of the continuous spectrum, a tentative decay scheme is discussed in section 6.
