摘要: Abstract Wide-spreading use of mini-orange electron spectrometers in conversion spectroscopy necessitates the standardization a few commonly available radio-isotopes for transmission calibration spectrometer. With this motivation, intensities electrons emitted following 125 Sb, 152 Eu and 160 Tb decays have been investigated using precisely calibrated Some experimental aspects optimization are discussed. In addition, results many weak transitions reported first time.
