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
- 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.
- The resolution capacity of the measurement layout is measured
from the half-life width of the principal peak.
What you can learn about
- Energy level diagram (decay diagram)
- Transition probability
- Excited nuclear states
- γ-emission
- Connection between the fine structure of the α-spectrum and the
accompanying γ-spectrum
