Nuclear physics and elementary particles

Quadrupole interaction , the interaction of systems of charged particles that is due to these systems having a quadrupole moment (see Quadrupole ).

Mesons , unstable elementary particles belonging to the class of hadrons; unlike baryons, mesons carry no baryon charge and have zero or integer spin (they are bosons).

Nuclear astrophysics covers the study of all the nuclear processes that take place in stars and in other cosmic objects.

A spatially unbounded homogeneous system of nucleons in a state that is stable against spontaneous expansion or compression.

The body of methods for studying atomic nuclei by the radiation that accompanies nuclear transformations and the transitions of nuclei from one state to another.

Nuclear physics - the branch of physics devoted to the study of the structure of the atomic nucleus, the processes of radioactive decay and the mechanism of nuclear reactions.

Nuclear photographic emulsion - a photographic emulsion for recording the trajectories (tracks) of charged particles.

Nuclear electronics is the body of methods of nuclear physics in which electronic instruments are used to record, convert and process the information coming from particle detectors.

Yukawa potential , a potential of the form Cexp(-μr)/r, where r is the distance between the particles and C and μ are constants; it describes the interaction of two particles that arises because they exchange an intermed…

(from the English charm), the same as mesons with hidden "charm".

Lagrangian , the analogue of the Lagrange function of a classical physical field in quantum field theory (QFT).

A charged-particle storage device (storage ring), an element of a colliding-beam system, consisting of a ring-shaped vacuum chamber in a magnetic field in which particles from a large number of charged-particle accelerat…

Neutron moderation , the reduction of the kinetic energy of neutrons as a result of their repeated collisions with atomic nuclei.

Charge conservation law , one of the fundamental exact laws of nature, which states that the algebraic sum of the electric charges of any closed (electrically isolated) system remains unchanged, whatever processes take p…

At the Lawrence Livermore National Laboratory in the USA, construction has been completed of the world's most powerful laser – the National Ignition Facility. $3.5 billion was spent on the needs of the project, and build…

For many years physicists in many countries have been working on a technique that would make it possible to run a thermonuclear reaction and at the same time to gain more energy than was spent on driving the process.

The European Organization for Nuclear Research is starting new work under the programme “Future Circular Collider”.

Cecil Frank Powell (5.12.1903-9.08.1969) was an English physicist and a Fellow of the Royal Society (1949).
