## Introduction to Nuclear Physics:

Nuclear physics is a branch of science that focuses on the study of the atomic nucleus—the core of an atom where protons and neutrons are densely packed. It delves into the fundamental forces, interactions, and properties that govern the behavior of atomic nuclei.

**Nuclear Structure and Models**:

Investigate the internal structure of atomic nuclei and the various models, such as the shell model and liquid-drop model, used to describe nuclear properties, including binding energies and nuclear shapes.

**Nuclear Reactions and Cross Sections**:

Delve into the study of nuclear reactions, which involve the interactions between atomic nuclei, and the determination of reaction cross sections, which play a vital role in astrophysics, nuclear energy production, and nuclear medicine.

**Nuclear Astrophysics**:

Focus on the application of nuclear physics principles to understand the processes occurring in stars, including nucleosynthesis, stellar evolution, and supernova explosions, which shape the chemical composition of the universe.

**Nuclear Fusion and Fission**:

Examine nuclear fusion, the process that powers the sun and holds potential for clean energy production, and nuclear fission, the basis for nuclear reactors and nuclear weapons, and their associated challenges and advancements.

**Nuclear Medicine and Radiation Therapy**:

Explore the applications of nuclear physics in medical imaging, such as positron emission tomography (PET) scans, and in cancer treatment through radiation therapy, highlighting the role of radioisotopes.
