Short Answer
Goeppert Mayer and Jensen is the best answer.
Nuclear and particle questions tend to hinge on conservation laws, decay rules, interaction types, or scale. A clean answer usually comes from identifying the process before the details.
Maria Goeppert Mayer and J.H.D. Jensen developed the nuclear shell model (1949), explaining magic numbers via spin–orbit coupling.
Why This Answer Is Correct
This is a Medium-level question in Nuclear & Particle Physics. The prompt is really testing whether you can connect the concept to its defining physical relationship instead of picking a nearby-but-wrong term.
Track conserved quantities carefully: energy, momentum, charge, lepton number, baryon number, and spin-like constraints when relevant.
Choices At A Glance
- A. Bohr and Mottelson
- B. Wigner and Fermi
- C. Goeppert Mayer and Jensen
- D. Rutherford and Soddy
When similar options appear on an exam, eliminate the ones that break the core law, use the wrong units, or confuse a definition with a consequence.
