Emission intensities of gamma transitions in 235U alpha decay
Original language description
New experimental values for the gamma-ray emission intensities in the decay of 235U have been obtained by measurements of a 230-g certified triuranium octoxide sample enriched in 235U to 93.2% with a 70 cm3 high-purity germanium detector over 1111 h. Calibration of energy scale and detection efficiency was performed by using peaks of 235U, 234mPa, and U/Th series daughters. The revised intensities account for cascade summation, random coincidences, and interference from gamma-rays of other nuclides. Intensities of several gamma transitions were found to have been significantly overestimated in earlier studies, by up to two orders of magnitude.
