The proposal to use pulsars as gravitational wave (GW) detectors was originally made by Mikhail Sazhin [4] and Steven Detweiler [5] in the late 1970s. The idea is to treat the solar system barycenter and a galactic pulsar as opposite ends of an imaginary arm in space. The pulsar acts as the reference clock at one end of the arm sending out ...
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 ...
The J/ψ (J/psi) meson / ˈ dʒ eɪ ˈ s aɪ ˈ m iː z ɒ n / is a subatomic particle, a flavor-neutral meson consisting of a charm quark and a charm antiquark.Mesons formed by a bound state of a charm quark and a charm anti-quark are generally known as "charmonium" or psions. [1]
In atomic physics and quantum chemistry, Hund's rules refers to a set of rules that German physicist Friedrich Hund formulated around 1925, which are used to determine the term symbol that corresponds to the ground state of a multi-electron atom. The first rule is especially important in chemistry, where it is often referred to simply as Hund's ...
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.
