• Absorption spectra of RbF-CsF solid solutions were measured at liquid ni-trogen temperature in the energy region 9-12 eV with the purpose to assign thesharp peaks near the fundamental absorption edge in CsF. The first peaks inRbF at 9.46 eV and in CsF at 9.22 eV merge into a single peak in solid solutions.The second peak in RbF at 11.01 eV disappears with the increase in the CsFcontent and does not connect with the second (9.34 eV) nor with the third peak(11.31 eV) in CsF. It is suggested that the first peak in CsF is due to the f-excitonand the second peak to the ,X'-exciton.
