The splitting of I 1 (2.3758 eV) and I 2 (2.3590 eV) lines observed in luminescence at liquid helium temperature due to uniaxial stress is investigated. The I 1 line splits into three components, all of them allowed for both polarizations. The I 2 line splits into two components, one allowed for ℰ⟂ p and the second allowed for both polarizations. The I 1 and I 2 lines are interpreted as due to radiative annihilation of excitons bound to neutral acceptor and donor, respectively.
