Abstract

Let XX be a smooth complex projective rationally connected threefold with KX-K_X nef and not semi-ample. In our previous work, we classified all such threefolds when KX|{-}K_X| has no fixed divisor. In this paper, we continue our classification when KX|{-}K_X| has a non-zero fixed divisor.
