Measurement of the velocitymomentumenergy
relations of relativistic electrons and determination
of e/m. Energetic electrons from the beta decay
of ^{90}SR and its decay
product ^{90}Y are sorted
according to momentum by a 180 degree magnetic
spectrograph, passed through a velocity selector,
and detected by a PIN diode detector.
Plots of momentum and energy
vs. velocity are compared with the theoretical
relations of classical and relativistic dynamics,
and the value of the ratio e/m is derived from
the data.
