By using adjunction theory, we describe the smooth complex projective threefolds admitting a simple normal crossing divisor of the form A+B among their hyperplane sections, both components A and B being smooth surfaces with sectional genus 0, and one of them being nef or at worst an exceptional divisor of the first reduction mapping.

Abstract
By using adjunction theory, we describe the smooth complex projective threefolds admitting a simple normal crossing divisor of the form A+B among their hyperplane sections, both components A and B being smooth surfaces with sectional genus 0, and one of them being nef or at worst an exceptional divisor of the first reduction mapping.
