Nuclear Physics:

Introduction:

Atomic nuclei, their components, and interactions, as well as other types of nuclear matter, are all studied in the discipline of physics known as nuclear physics.

 

Atomic physics, which examines the atom in its entirety, including its electrons, should not be confused with nuclear physics.

 

Applications in numerous domains have been made possible by nuclear physics discoveries. This covers radiocarbon dating in geology and archaeology, nuclear medicine, nuclear medicine and magnetic resonance imaging, industrial and agricultural isotopes, ion implantation in materials engineering, and nuclear power. In the discipline of nuclear engineering, these applications are researched.

 

Nuclear physics gave rise to particle physics, and the two disciplines are frequently taught in tandem. In order to understand the inner workings of stars and the genesis of the chemical elements, nuclear astrophysics, or the application of nuclear physics to astronomy, is essential.

Background:

The history of radioactivity as a field of study apart from atomic physics dates back to Henri Becquerel's discovery of it in 1896 while he was looking into the phosphorescence of uranium salts. The atom's internal structure was revealed by J. J. Thomson's discovery of the electron a year later. J. J. Thomson's "plum pudding" concept, in which the atom was a positively charged ball with tiny negatively charged electrons lodged inside of it, was the recognised model of the atom at the beginning of the 20th century.

 

Radioactivity was thoroughly studied in the years that followed, particularly by Marie and Pierre Curie, Ernest Rutherford, and other scientists. The three types of radiation that come from atoms that were discovered by physicists around the turn of the century were alpha, beta, and gamma radiation. Otto Hahn's and James Chadwick's experiments from 1911 and 1914 respectively revealed that the beta decay spectrum was continuous as opposed to discrete. This means that rather than the discontinuous amounts of energy seen in gamma and alpha decays, electrons were released from the atom with a continuous spectrum of energies. At the time, this presented a challenge for nuclear physics because it appeared to show that energy was not conserved in these decays.

 

Becquerel received the 1903 Nobel Prize in Physics for his discovery, while Marie and Pierre Curie received it for their later study of radioactivity. For his "investigations into the breakdown of the elements and the chemistry of radioactive substances," Rutherford received the Nobel Prize in Chemistry in 1908.

 

Albert Einstein first proposed the concept of mass-energy equivalence in 1905. Although Becquerel and Marie Curie's research on radioactivity came before this, it wasn't until scientists realised that the nucleus itself was made up of smaller particles called nucleons that the energy of radioactivity could be explained.
