Abstract: | New optical spectra near the fundamental edge of GaSe have been measured at low temperatures. The observed fine structure is explained in terms of transitions to excitonic groundstates and excited states, in terms of phonon replica of exciton ground states and in terms of excitons bound to intrinsic point defects. |
