A general class of similarity integrals of the Ernst equation with the method of Chandrasekhar and Xanthopoulos are combined to obtain a family of solutions for colliding waves in the Einstein–Maxwell theory. The family is parametrized by an arbitrary harmonic function that satisfies the Euler–Darboux equation. The first nontrivial member of the family is shown to be the cross‐polarized version of the Bell–Szekeres solution.
