  We employ WKB approximation up to the third order to determine the low-lying
quasinormal modes for Weyl neutrino field in R-N black holes, which are the
most relevant to the evolution of the field around a black hole in the
intermediate stage. It is showed that the quasinormal mode frequencies for Weyl
neutrino field in R-N black holes are different from those in Schwartzchild
black holes owning to the charge-induced additional gravitation, and the
variations of the quasinormal mode frequencies for Weyl neutrino field are
similar to those for integral spin fields in R-N black holes.
