Va. Morozov et al., A new method for measuring gamma-ray energy at the internal calibration ofa radioactive source, INSTR EXP R, 43(3), 2000, pp. 300-305
We developed a new method for measuring gamma-ray energies in the internal
calibration of a radioactive source under investigation. The measurements w
ere carried out with the spectrometer of delayed coincidences and an optica
l delay line. This method allows the energies of the reference peak and the
gamma-ray peak under investigation to be compared, even if they are close
or coincide. The possibility of precise gamma-ray energy measurements is il
lustrated with Co-60 and Eu-154 isotopes.
