Abstract: We calculate explicitly the Betti numbers of a class of barely G2 manifolds -that is, G2 manifolds that are realised as a product of a Calabi-Yau manifoldand a circle, modulo an involution. The particular class which we consider arethose spaces where the Calabi-Yau manifolds are complete intersections ofhypersurfaces in products of complex projective spaces and the involutions arefree acting.
