11.4 Photoneutrino emission
This process differs from the plasmon decay described in Section 11.3, by the participation of an
The process was proposed by Ritus [347, 348] and Chiu & Stabler ; the most recent formulae for
were derived by Itoh et al. [215, 216, 217]. Formula (263) implies that if then
. Therefore, is exponentially suppressed with decreasing temperature or increasing
density. Additional damping of results from electron degeneracy. However, if electrons are
nondegenerate, can be stronger than .
