spin filter

spin filter

[′spin ‚fil·tər]
(electronics)
A device used in a Lamb-shift polarized ion source to cause those atoms having an undesired nuclear spin orientation to decay from their metastable state to the ground state, while those with the desired spin orientation are allowed to pass through without decay.
