About Radioactive Elements

About Radioactive Elements Definition Radioactive element does not have any stable isotopes, which means it may spontaneously degenerate. Radioactive elements include uranium, curium and thorium. Radioactive elements are just like the other elements. They are made of neutrons, protons, and electr.....

About Cyclotron

About Cyclotron Definition Cyclotron is a type of particle accelerator that uses a constant magnetic field to hold charged particles in a circular spiral pattern. The first cyclotron was invested at the University of California, Berkeley, in 1932, by Ernest Lawrence in collaboration with his stud.....

About Antiproton

About Antiproton Definition Antiproton is actually stable but still of short life as any collision with proton means destruction of both with sudden burst of energy. It is also called negatron. Antiprotons were first produced and identified in 1955 by Emilio Segrè, Owen Chamberlain, for which th.....

About Bubble Chamber

About Bubble Chamber Definition Bubble Chamber is a chamber of superheated liquid in which the path of an ionizing particle is made visible by a string of vapor bubbles. It is designed to detect charged particles through the tracks of bubbles present in a chamber consisting of liquefied gas or li.....

About Gamma Radiation

About Gamma Radiation Definition Gamma Radiation is very high-energy ionizing radiation. Gamma rays originate in the nucleus, while X-rays originate in the electron cloud around the nucleus. Gamma-rays are a form of electromagnetic radiation, as are radio waves, infrared radiation, ultraviolet ra.....

Ferromagnetism in Physics

Ferromagnetism in Physics Introduction Ferromagnetism, physical phenomenon in which certain electrically uncharged materials strongly attract others. Two materials found in nature, lodestone or magnetite, an oxide of iron, Fe3O4 and iron, have the ability to acquire such attractive powers, and th.....

Antiferromagnetism in Physics

Antiferromagnetism in Physics Antiferromagnetism means that the electrons within the material do not align themselves with the same magnetic polarity. Even within the specific domains, the material does not display any magnetic qualities. As a result of the electrons not aligning themselves in th.....

Pauli Exclusion Principle

Pauli Exclusion Principle Definition The Pauli Exclusion Principle states no two electrons or other fermions can have the identical quantum mechanical state in the same atom. In the case of electrons in atoms, it can be stated as follows: it is impossible for two electrons of a poly-electron atom.....

About Wavefunction

About Wavefunction Defionition A wave function is a function that encodes the state of a quantum-mechanical system. Typically the wave function obeys a wave equation or modified wave equation that has wave-like solutions, hence the name. The wave function is a function of the degrees of freedom c.....
