spin-orbit coupling جفسری ِ اسپین-مدار، جفتش ِ ~ jafsari-ye espin-madâr, jofteš-e ~ Fr.: couplage spin-orbite - Astro.: A relationship between the orbital period of one body around another
and its rotational period on its axis. The relationship results from tidal forces
between the two bodies. For example, the rotation period of the Moon equals its revolution
period around the Earth.
- Quantum mechanics:
The interaction between a particle’s → spin angular momentum
and its → orbital angular momentum.
