Abstract

We present for the first time two-photon measurements on rutile Sn

O_{2}

. The detailed polarization analysis yields

{Γ_{3}}^{+}

symmetry for the direct forbidden

1 S

exciton and the upper valence band. Our results clear up the long-standing controversy concerning the symmetry of the upper valence band.
