Nuclear force – field quantum<br />

photon carries the electromagnetic force.<br />

Analogy: postulate particle as carrier of nuclear<br />

force (Hideki Yukawa, 1935) with mass intermediate<br />

between the electron and the proton<br />

This particle also to be responsible for beta-decay.<br />

potential energy between the nucleon field quanta<br />

has the form<br />
