Energy and cross sections

In summary, energy is the ability to do work or cause change and can exist in different forms. Energy and cross sections are related in the context of nuclear reactions and particle collisions, where the amount of energy involved affects the size of the cross section. A cross section is a measurement of the effective area of a target for a given type of interaction. In scientific research, cross sections are important in understanding and predicting the behavior of particles and their interactions, providing valuable information about the fundamental properties of matter. Energy is transferred in a cross section through interactions between particles, resulting in changes in their motion or states of matter.

I was wondering whether there's any interactions or productions that has cross section that doesn't only increase monotonously with energy, but has a drop somewhere at certain energy scales ?

Neutron cross-sections are in general quite irregular when considering interation with various nuclei, especially heavy ones.

Gamma-ray cross sections also have some irregularity (in the kev range) due to certain resonances.

What is energy?

Energy is the ability to do work or cause change. It is a property of matter and can exist in many forms, such as kinetic, potential, thermal, and electromagnetic.

How are energy and cross sections related?

Energy and cross sections are related in the context of nuclear reactions and particle collisions. In these events, the amount of energy involved affects the size of the cross section, which is a measure of the probability of an interaction occurring.

What is a cross section?

A cross section is a measurement of the effective area of a target for a given type of interaction. In the field of nuclear and particle physics, it is commonly used to describe the probability of a collision or reaction occurring between particles.

How is energy transferred in a cross section?

Energy is transferred in a cross section through interactions between particles. When particles collide or interact, they can transfer energy to one another, resulting in changes in their motion or states of matter.

Why are cross sections important in scientific research?

Cross sections are important in scientific research because they provide valuable information about the fundamental properties of matter and the nature of interactions between particles. They are essential in understanding and predicting the behavior of particles in various physical systems, such as nuclear reactors and particle accelerators.
