Influence of the finite dimensions of the nucleus on the relative conversion coefficients in the L-subshells

Abstract Measurements have been made of the relative interval conversion coefficients in the L-subshells for three pure MI transitions: 46.5 keV in Bi 210 , and 115.1 and 238.6 keV in Bi 212 . It is shown that in order to obtain agreement with the experimental data, it is necessary to take into consideration the finite dimensions of the nucleus in the theoretical calculations of the L interval conversion coefficients. Measurements have also been made of L I : L II : L III for the 277.3 keV Ml transition in Pb 208 .
