The same convention is also used, although with some few exceptions, by optical astronomers working in the field of polarimetry. Many radio astronomers, on the other hand, use the opposite convention.

W. Demtröder, "Atoms, molecules and photons", 2006, Springer, sec. 3.1, p. 91. The author uses the optics convention. "If left circularly-
polarized light (σ+-polarization) propagating in the z
direction is absorbed by atoms, the z component of
their angular momentum Jz is changed by ∆Jz = +ℏ".
