Abstract

We show that the complete intersection V = V (2, 3) ! P5 of a quadric and a cubic in 5-dimensional projective space defined over a field k, of char. "= 2, 3, is unirational over this field k itself if moreover V has a point p rational over k and if one of the two planes through p on the quadric is also rational over k.
