Popis:	Luminescence produced by the decay of excitons bound to neutral boron acceptors in diamond is reported at higher resolution than hitherto. The line-widths of the phonon-assisted processes are consistent with the electron and hole of the bound exciton having a spatial localization within an effective Bohr radius of about 0.85 nm. New fine structure is reported in the no-phonon components of the luminescence, caused by splittings in both the ground and excited states of the localized particles.
