  2. Relativistic Breit–Wigner distribution - Wikipedia

    en.wikipedia.org/wiki/Relativistic_Breit–Wigner...

    In experiment, the incident beam that produces resonance always has some spread of energy around a central value. Usually, that is a Gaussian/normal distribution.The resulting resonance shape in this case is given by the convolution of the Breit–Wigner and the Gaussian distribution,

  3. Isoscalar - Wikipedia

    en.wikipedia.org/wiki/Isoscalar

    In particle physics, isoscalar refers to the scalar transformation of a particle or field under the SU(2) group of isospin. [1] Isoscalars are a singlet state, with total isospin 0 and the third component of isospin 0, much like a singlet state in a 2-particle addition of spin.

  4. Resonances in scattering from potentials - Wikipedia

    en.wikipedia.org/wiki/Resonances_in_scattering...

    In quantum mechanics, resonance cross section occurs in the context of quantum scattering theory, which deals with studying the scattering of quantum particles from potentials. The scattering problem deals with the calculation of flux distribution of scattered particles/waves as a function of the potential, and of the state (characterized by ...

    en.wikipedia.org/wiki/Resonance_(particle_physics)

    In particle physics, a resonance is the peak located around a certain energy found in differential cross sections of scattering experiments. These peaks are associated with subatomic particles , which include a variety of bosons , quarks and hadrons (such as nucleons , delta baryons or upsilon mesons ) and their excitations .

  7. Laser detuning - Wikipedia

    en.wikipedia.org/wiki/Laser_detuning

    In optical physics, laser detuning is the tuning of a laser to a frequency that is slightly off from a quantum system's resonant frequency.When used as a noun, the laser detuning is the difference between the resonance frequency of the system and the laser's optical frequency (or wavelength).

  8. Resonance (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Resonance_(chemistry)

    Contributing structures of the carbonate ion. In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, [1] also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.

  9. Thin-film bulk acoustic resonator - Wikipedia

    en.wikipedia.org/wiki/Thin-film_bulk_acoustic...

    With the development of thin film technologies it was possible to keep the Q factor high enough, leave out the crystal and increase resonance frequency. Ladder type bandpass filter based on FBAR resonators. The difference of resonance frequency of resonators 1 and 2 determine the frequency range of frequencies to be passed.
