lnternal and external conversion spectra from the decay of Pb/sup 203/ were studied in a double-focusing beta spectrometer. The internal conversion coefficients of the 279- and 401-kev transitions were determined by comparing the intensities of the internal conversion- and the photo-lines and calculating the correction factors for the anisotropy of the photoelectric emission according to the method of Hultberg. The accuracy of the method is discussed. The directional correlation gamma - e/sub k bar/ for the 401- to 279-kev cascade was measured in thc double-focusing beta spectrometer. The results are discussed in connection with the nuclear structure effects on the internal conversion process, which are expected to show up in the retarded 279-kev transition (M1, l-forbidden). In the sceond part of this study the K - LL, -LM, - LN,-MM, -MN, and NN Auger spectra of T1 were measured using an isotope separated Pb/sup 203/ sample. The relative intensities of the lines or line groups were determined and the results were compared with the theory of Asaad and Burhop (non- relativistic) and of Asaad (rehativistic). (auth)
