• Highly sensitive momentum-space spectroscopy, named two-photon polariza-tion spectroscopy (TPPS), is presented in the Z. exciton resonant region of Curl.This spectroscopy is based on the induced optical anisotropy associated with theformation of T. excitonic molecules (EM's). By this method the following factsare confirmed : the upper branch polaritons (UBP's) and the lower branch polari-tons (LBP's) coexist in the wide energy range above the longitudinal excitonenergy; the conversion of UBP into LBP occurs in the reflection at the sampleboundary; the EM relaxation depends on the wave number in the large wavenumber region. From the quantitative analysis of the spectra, it has been foundthat the damping of the Z. exciton depends strongly on its energy in the L-T gapregion. The prospects of the ABC problem are also discussed.
