The nucleus is held together by a force. It was predicted that a particle exists that is
responsible for this force. The particle itself must experience this force.
The particle would have a rest energy between that of an electron and half that of a
nucleon.
Discuss whether a kaon, a muon and a pion each have the properties of the predicted
particle.
Information about these three particles is in the Data and Formulae Booklet.
