New mechanism for spin-flip scattering in spin-polarized gases
Bashkin E. P.
A new exchange mechanism is proposed for transport phenomena which occur in spin-polarized systems and which are accompanied by a spin flip of the scattered particle and the emission or absorption of a collective spin wave. The corresponding scattering cross section turns out to be anomalously large. This circumstance may strongly influence the stability of Η Τ and Dt and may lead to giant effects in neutron optics.
