hyperfine interaction energy
1Energy level — A quantum mechanical system or particle that is bound that is, confined spatially can only take on certain discrete values of energy. This contrasts with classical particles, which can have any energy. These discrete values are called energy… …
2Hyperfine structure — In atomic physics, hyperfine coupling is the weak magnetic interaction between electrons and nuclei. Hyperfine coupling causes the hyperfine splitting of atomic or molecular energy levels. The totality of energy levels spawned by hyperfine… …
3hyperfine structure — /huy peuhr fuyn , huy /, Physics. the splitting of the lines of an atomic spectrum, produced by the angular momentum of the nucleus of the atom. Cf. fine structure. [1925 30; HYPER + FINE1] * * * ▪ physics in spectroscopy, the splitting of… …
4Interaction gravitationnelle de l'antimatière — L interaction gravitationnelle de l antimatière avec la matière ou avec l antimatière n a pas été observée par les physiciens dans des conditions permettant d en tirer des conclusions. Un consensus écrasant règne parmi les physiciens selon lequel …
5Fermi contact interaction — Not to be confused with Fermi s interaction . The Fermi contact interaction is the magnetic interaction between an electron and an atomic nucleus when the electron is inside that nucleus. It is of magnitude and where U is the energy of the… …
6RKKY interaction — RKKY stands for Ruderman Kittel Kasuya Yosida and refers to a coupling mechanism of nuclear magnetic moments or localized inner d or f shell electron spins in a metal by means of an interaction through the conduction electrons. The RKKY… …
7Gravitational interaction of antimatter — The gravitational interaction of antimatter with matter or antimatter has not been conclusively observed by physicists. While the overwhelming consensus among physicists is that antimatter will attract both matter and antimatter at the same rate… …
8Crystallographic defects in diamond — Synthetic diamonds of various colors grown by the high pressure high temperature technique, the diamond size is 2 mm …
9Mössbauer effect — Physics. the phenomenon in which an atom in a crystal undergoes no recoil when emitting a gamma ray, giving all the emitted energy to the gamma ray, resulting in a sharply defined wavelength. [1955 60; named after R. MÖSSBAUER] * * * ▪ physics… …
10Rotational spectroscopy — Part of the rotational vibrational spectrum of carbon monoxide (CO) gas (from FTIR), showing the presence of P and R branches. Frequency is on the x axis, and absorbance on the y axis. Rotational spectroscopy or microwave spectroscopy studies the …
