The internal K-conversion coefficients of 7 transitions following the decay of Bi/sup 203/ (including the 279.1-kev transition in Tl/sup 203/) and 5 transitions from the decay of Bi/sup 204/ were determined absolutely by the method of comparing internal and external conversion lines measured in a double- focusing spectrometer. The multipolarity assignments based on these values are, in cases where a comparison is possible, in agreement with the assignments suggested from the measured intenual conversion ratios or other data. Complementary measurements of energies and intensities of low-energy conversion lines in Pb/sup 203/ were carried out in the double-focusing spectrometer. The level scheme of Pb/sup 203/ is discussed. The half-lives of Bi/sup 203/ and Bi/ sup 204/ were remeasured and found to be -- 0.05 hr and 11.22 plus or minus 0.10 hr, respectively. (auth)
