Study of the alpha-energies of 226Ra with xyt writer
Principle: An α-spectrometer, consisting of a silicon surface barrier layer detector, a preamplifier, a pulse height analyser and a recording device for registration of the spectra is calibrated by means of an open α-emitter of known α-energy (241Am). The energy spectrum of a radium source which is in equilibrium with its decay products, is recorded and evaluated. The α-energies found in this way are allocated to the corresponding nuclides of the radium decay series.
Tasks:
1. The α-spectrum of the 226Ra is recorded, the settings of the pulse analyzer (amplification) and recorder (x and y input sensitivity) being selected so as to make best possible use of the recording width.
2. The calibration spectrum of the open 241Am-emitter is recorded at the same settings.
3. The α-energies corresponding to the individual peaks of the α-spectrum of the radium are calculated and, on the assumption of a constant energy loss in the source covering, the α-active nuclides of the radium decay series corresponding to the individual peaks are determined on the basis of the values in the literature.
