“…The photons emitted in the 1~ l~ electron capture decay were measured by means of the windowless 47z scintillation counter [10] with two NaI(T1) crystals. A solid source, mounted as a sandwich inside polyethylene foils, was inserted between the crystals.…”

The internal conversion coefficients were measured for the 88.032keV E3 transition in ~~ using the 4re pressurized proportional counter, the windowless 4n scintillation counter and the double-focusing magnetic spectrometer. The results are: a T = 26.4 _+ 0.4, ~K=11.4_+0.3, ~L, = 0.63 _+ 0.13, C~L2 = 5.48 ___ 0.18 , C~L3=6.11___0.20 , C~M = 2.40 __ 0.08 , C~NO= 0.405 +0.021. The theoretical conversion coefficients were calculated for this transition and for the 391.69 keV M4 transition in 113In and were found to be in agreement with the experiment.
