Sorry, no etymologies found.
Without good control, the electrons are emitted with a range of energies and momenta, meaning that they are not all focused to the same location by the electron optics.
I'm working on a couple of books at the momenta crime story set in Sri Lanka and a sequel to A Guide to the Birds of East Africa.
If it exists its mass will be measured from the energy and momenta of its decay products.
In the cosmology/astrophysics community, dark matter was proposed because observations of galactic angular momenta disagreed with existing theory.
There is also evidence supporting the conjecture that the equivalence principle is valid separately for quarks and gluons resulting in exact equipartition of momenta and angular momenta in the nucleon.
Next, identify pairs of canonical conjugate variables, such as coordinates and momenta for pointlike particles (Ch. 21.2), the angular variables φ and cosθ for spins, or whatever.
I remember only the waking, Bayard shaking me back into light and cold and pain, and into a sadness I did not recognize for a momenta sadness I could not place until I saw the centaur bodies and remembered.
Therefore, the energy and momentum of the empty conduction band state is equal to or less than the sum of the momenta and energies of the electron in the valence band, the photon from the sun, and the phonon from the crystal lattice.
So we put it into the ratio of angular momenta amd L/L' ~ .14 .
A rough estimate could consider the ratio of the angular momenta of the sun to Jupiter
