In this paper, we study the geometry of Einstein half lightlike submanifolds $M$ of a semi-Riemannian space form $\bar{M}(c)$ subject to the conditions: (a) $M$ is screen conformal, and (b) the coscreen distribution of $M$ is a conformal Killing one. The main result is a classification theorem for screen conformal Einstein half lightlike submanifolds of a Lorentzian space form with a conformal Killing coscreen distribution.

Keywords: half lightlike submanifold, screen conformal, conformal Killing distribution
