In atomic physics, spin–orbit coupling, also known as spin-pairing, describes a weak magnetic interaction, or coupling, of the particle spin and the orbital motion of this particle, e.g. the electron spin and its motion around an atomic nucleus. One of its effects is to separate the energy of internal states of the atom, e.g. spin-aligned and ...
In physics, a pair potential is a function that describes the potential energy of two interacting objects solely as a function of the distance between them. [ 1 ] Some interactions, like Coulomb's law in electrodynamics or Newton's law of universal gravitation in mechanics naturally have this form for simple spherical objects.
In chemistry, ion association is a chemical reaction whereby ions of opposite electric charge come together in solution to form a distinct chemical entity. [1] [2] Ion associates are classified, according to the number of ions that associate with each other, as ion pairs, ion triplets, etc. Ion pairs are also classified according to the nature of the interaction as contact, solvent-shared or ...
December 6, 2024 at 6:28 AM The Village People’s lyricist and lead singer has hit out at the “false assumption” that the band’s biggest hit, “ YMCA ,” is a “gay anthem.”
Larger arrays may be better for GW detection because the quadrupolar spatial correlations induced by GWs can be better sampled by many more pulsar pairings. With such a GW detection, millisecond pulsar timing arrays would open a new low-frequency window in gravitational-wave astronomy to peer into potential ancient astrophysical sources and ...
Going for a quick walk after eating really can help improve digestion and energy, a dietitian says. Walking helps to control blood sugar levels and circulates nutrients.
California voters on Tuesday approved a November ballot measure that will impose stricter penalties for repeat theft and crimes involving fentanyl, steering away from recent progressive policies ...
The Breit–Wheeler process is the creation of an electron–positron pair following the collision of two high-energy photons (gamma photons). The nonlinear Breit–Wheeler process or multiphoton Breit–Wheeler is the creation of an electron-positron pair from the decay of a high-energy photon (gamma photon) interacting with a strong electromagnetic field such as a laser.
