temperature, and for thermal neutrons produced by a neutron source. For massive, non-interacting particles, the thermal de Broglie wavelength can be derived...

A pulsar (from pulsating radio source) is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic...

Dispersion stabilized molecules are molecules where the London dispersion force (LDF), a non-covalent attractive force between atoms and molecules, plays...

produced by related scattering techniques such as electron diffraction or neutron diffraction. If single crystals of sufficient size cannot be obtained,...

transverse optical phonons, this is due to the particular form of the dispersion relation of the phonon and photon and their interaction. Photons consist...

limit (or TOV limit) is an upper bound to the mass of cold, non-rotating neutron stars, analogous to the Chandrasekhar limit for white dwarf stars. Stars...
