Beta Decay Curve

  1. Apr 21, 2007 #1
    Hi all,

    Why is the beta decay graph( no. of Beta particle vs Kinetic energy) a curve(or sort of bell shape). I understand that neutrinos are emitted, even so shouldn't the KE be a constant value?

    You probably mean a curve of number of events vs electron KE.
    Since the decay is into three bodies, conservation of energy and momentum does not give a single value for the electron energy.
