Yukawa’s theory of nuclear forces
- A little over 50 years ago, Hideki Yukawa, a young Japanese theoretical physicist at the University of Osaka, proposed a fundamental theory of nuclear forces involving the exchange of massive charged particles between neutrons and protons.
- He called the exchanged particles “heavy quanta” to distinguish them from the light quanta of the electromagnetic field, but now they are known as pions, the lightest members of a large family of particles called mesons.
EXPLANATION:
- According to Yukawa’s theory of nuclear forces, the origin of nuclear force between nucleons is due to the exchange of mesons.
- Hence, option 1 is correct.
