Principle

The radiation of β-unstable atomic nuclei is selected on the
basis of its pulses in a magnetic transverse field, using a
diaphragm system. The relationship between coil current and
particle energy is determined for calibration of the spectrometer
and the decay energy of the β-transition is obtained in each case
from the β--spectra.

Tasks


Energy calibration of the magnetic spectrometer.
