SHORT COMMUNICATION: Determination of the Manganese K-shell Fluorescence Yield from the 55Fe Decay
Abstract
The manganese K-shell fluorescence yield (ωK) in the 55Fe decay for two thermally evaporated sources was measured using absolute measurement methods for the activity and the K X-ray emission rate with the national primary standard at VNIIM.
The mean value obtained is ωK = 0.312 +/- 0.003 which agrees with a semiempirical value of ωK = 0.314 +/- 0.023 within the limits of measurement uncertainty.- Publication:
