What is nuclear physics?

Nuclear physics is a branch of physics that studies the structure, properties, and behavior of atomic nuclei and the fundamental forces and particles involved. It explores phenomena such as radioactivity, nuclear reactions, and the interactions between protons and neutrons within the nucleus. Nuclear physics has many practical applications, including nuclear energy production, medical imaging (such as PET scans), and cancer treatments (radiation therapy). Researchers in this field use both experimental and theoretical approaches to understand nuclear matter and its role in the universe.
