multiplet
multiplet (ˈmʌltɪplət) [f. multiple a. and n. + -et, after doublet, triplet.] a. A group of lines in a spectrum that are close together and spaced approximately in accordance with a simple rule; a group of related levels in an atom that differ slightly in energy, esp. a group in which this is due to...

Multiplet
Thus, a multiplet has also come to describe a collection of subatomic particles described by these representations. In QCD, quarks are in a multiplet of SU(3), specifically the three-dimensional fundamental representation. wikipedia.org

Isospin multiplet
The set of these states is called isospin multiplet and is used to accommodate the particles. An example of an isospin multiplet is the nucleon multiplet consisting of the proton and the neutron. wikipedia.org

Doublet earthquake
In seismology, doublet earthquakes – and more generally, multiplet earthquakes – were originally identified as multiple earthquakes with nearly identical Multiplet events overlap in their focal fields (rupture zones), which can be up 100 kilometers across for magnitude 7.5 earthquakes. wikipedia.org

What is multiplet nuclei capture rate? I met this terminology in a publication.< It's in the last sentence of the second paragraph in the text. I tried to search for it but didn't get a conclusive definition. Is it an...
It is multiple nuclei capture rate. They talk about it in the supplementary section near the bottom of the article. They diluted the processed sample to get an estimated 2000 nuclei per microlitre. They then want the machinery to process individual nuclei, but cant tell from the results if two or mo...

Charlotte Moore Sitterly
Moore collaborated with Tousey for decades and led to her 1950 publication "Ultraviolet Multiplet Table." In 1949 she became the first woman elected as an associate of the Royal Astronomical Society of Great Britain, in honor of her work on multiplet tablets wikipedia.org

(ˈhaɪpətʃɑːdʒ) [f. hyper(onic) charge: see quot. 1956.] A property of hadrons that is conserved in strong interactions and is represented by a quantum number Y that is the same for all the particles of a charge multiplet (isospin multiplet), being equal to twice their av...

Multipolar exchange interaction
The example tells us, for a -multiplet problem, one will need all rank tensor operators to form a complete super basis. A cubic harmonic super basis where all the tensor operators are hermitian can be defined as Then, any quantum operator defined in the -multiplet Hilbert wikipedia.org

Pseudovector meson
The 1 multiplet of light mesons may show similar behavior to that of other vector mesons, in that the mixing of light quarks with strange quarks appears The 1 multiplet, on the other hand, may be affected by other factors that generally reduce meson masses. wikipedia.org

Hypercharge
Isospin creates multiplets of particles whose average charge is related to the hypercharge by: since the hypercharge is the same for all members of a multiplet Each multiplet consists of substates with equally-spaced values of Jz, forming a symmetric arrangement seen in atomic spectra and isospin. wikipedia.org

G-parity
We can generalize the C-parity so it applies to all charge states of a given multiplet: where ηG = ±1 are the eigenvalues of G-parity. Since G-parity is applied on a whole multiplet, charge conjugation has to see the multiplet as a neutral entity. wikipedia.org

George Pake
There, he discovered the multiplet structure produced by the dipolar coupling of two nuclear spins. In his honor, this multiplet is now known as the Pake doublet and forms the basis for NMR-based inter-atomic distance measurements and molecular structure wikipedia.org
