Low Energy Nuclear Physics:
Low-energy nuclear physics refers to the study of nuclear interactions at relatively small energies compared to the binding energy of atomic nuclei. In this range of energies, atomic nuclei are held together by the strong nuclear force, which is the strongest known interaction in nature. Low energy nuclear physics experiments are commonly performed in research laboratories and use particle accelerators to study the structure and properties of nuclei.
The study of nuclear structure is one of the main areas of research in low energy nuclear physics. Experiments in this area provide detailed information about the charge distribution, angular momentum, and spin of nuclei, which helps to understand the arrangement of protons and neutrons within nuclei. Nuclear decay and nuclear reactions caused by the interaction of particles with nuclei are also important topics in low-energy nuclear physics.
Another important field of study in this area is the production and study of radioactive isotopes. These isotopes play a crucial role in nuclear medicine, the dating of archaeological and geological materials, and in industrial applications, such as power generation in nuclear reactors.
High Energy Nuclear Physics:
High-energy nuclear physics, also known as particle physics, studies nuclear and subnuclear interactions at extremely high energy levels. These energy levels are frequently studied in large particle accelerators such as CERN's Large Hadron Collider (LHC). Elementary particle physics overlaps with nuclear physics in this energy range, where scientists seek to understand the fundamental forces and subatomic particles that make up matter.

Comparison and Complementarity:
Although high and low energy nuclear physics address different energy scales and phenomena, they are complementary and provide a more comprehensive picture of nuclear and subnuclear behaviour. While low-energy nuclear physics focuses on the internal structure of nuclei and nuclear interactions, high-energy nuclear physics seeks answers to fundamental questions about matter and the fundamental forces that govern the universe.
High and low energy nuclear physics is fundamental to understanding matter and the forces that act at the nuclear and subnuclear levels. High-energy nuclear physics explores new phenomena that may challenge the Standard Model and also explores nuclear structure and interactions. Together, these two research disciplines give us the opportunity to explore the enigmas of the cosmos, from the structure and evolution of atoms to the most basic particles that make up matter and energy.
Exercise on High and Low Energy Nuclear Physics
I propose you to analyze two nuclear physics experiments in this exercise: one related to high energy physics and the other related to low energy physics. These experiments will help you better understand the differences and similarities between these fields.
Low energy nuclear physics experiment: gamma spectroscopy
Objective: To measure the gamma radiation emitted during the decay of a radioactive isotope to investigate its internal structure and nuclear properties.
Description: We will use a research laboratory that has a gamma radiation detector and a sample of a radioactive isotope, such as Cesium-137. The sample is placed in the detector and the gamma radiation emitted by the nuclei as they decay is recorded.

High Energy Nuclear Physics Experiment: Collision of Nuclei at the LHC
Objective: Study nuclear interactions at extremely high energies through the collision of nuclei in the Large Hadron Collider (LHC).
Description: We will use the LHC, a particle accelerator located at CERN, to accelerate protons or heavy nuclei, such as lead ions, to speeds close to the speed of light. Then we will collide these nuclei at high energies.
Analysis: A stream of subatomic particles generated by high-energy collisions at the LHC will be detected by several detectors located around the collision points. Scientists will investigate the characteristics of the particles created, how momentum and energy are distributed, and how new states of matter are formed.
Importance: For high-energy nuclear physics, experiments at the LHC are crucial because they allow us to explore the structure of matter on subatomic scales and study phenomena such as the quark-gluon plasma, which represents the conditions of the universe shortly after the Big Bang. Additionally, these experiments look for hints of particles and phenomena outside of the Standard Model, which could have a significant impact on our understanding of the universe.
In this exercise, we have analyzed two experiments in nuclear physics, one high energy and one low energy. In low-energy nuclear physics, gamma spectroscopy allows us to study nuclear structure and properties, while in high-energy nuclear physics, the collision of nuclei at the LHC allows us to explore nuclear interactions and phenomena at subatomic scales.
Both fields of study are complementary and essential for our understanding of the fundamental forces that control the universe at different energy scales. High-energy nuclear physics seeks answers to fundamental questions and phenomena that may go beyond the Standard Model, while low-energy nuclear physics helps us understand the internal structure of nuclei and their decay behavior. These areas of research allow us to solve mysteries when we work together.
