Principle

The alpha-spectrum of an open 241Am-emitter is measured with a semiconductor a-detector. In connection with a multi channel analyzer the main parts of the spectrum are investigated.

Tasks

  1. The spectrum of an uncovered 241Am-emitter is recorded with the multi channel analyzer. The energies of the two peaks preceding the principal peak are calculated. The principal peak, corresponding to a particle energy of 5.486 MeV, is used for calibration purposes.
  2. The resolution capacity of the measurement layout is measured from the half-life width of the principal peak.
