Internal conversion in 137m Ba with MCA
Article No: P2524515
The radiation emitted during the decay of the 137Cs isotope is measured with a scintillation detector and the energyspectrum determined with a pulse height analyzer. The spectrum contains fractions due to a gamma-transition and fractions originating from a characteristic X-ray radiation. The areas of the fractions in question are determined and the conversion factor obtained from them. Tasks Measurement of the g-spectrum of 137Cs using a scintillation detector. Determination of the conversion factor of the 137mBa excited nucleus. Learning objectives g-radiation Nuclear transitions Transition probability Duration Metastable states Isotopic spin quantum Numbers Rules governing selection Multipole radiation Isomeric nuclei Photonuclear reaction Conversion electron Characteristic X-ray radiation Scintillation detectors
