nuclear physics
Quick Summary
Nuclear physics is the branch of physics that studies the structure of the atomic nucleus and the radiation emitted from unstable nuclei. The nucleus, located at the center of an atom, contains protons and neutrons and accounts for nearly all of the atom's mass.123
Within the nucleus, protons and neutrons are held together by a powerful force called the strong force. Unstable nuclei can undergo radioactive decay, releasing energy and subatomic particles such as alpha rays (helium nuclei), beta rays (electrons), and gamma rays (electromagnetic radiation). This process is fundamental to understanding phenomena like nuclear power generation, which harnesses the energy released from splitting atomic nuclei. Quantum theory is essential for comprehending nuclear structure and behavior.241567

The particle accelerators used in nuclear physics can be viewed as mass spectrometers of rather distorted forms, but the three principal elements—the ion source, analyzer, and detector—are always present. L.W. Alvarez and Robert Cornog of the United States first used an accelerator as a mass spectrometer in 1939 when they…
