Abstract
The properties of a recently discovered photoluminescence recombination pro cess, involving negatively charged donor ions (D-) in GaAs, are investigate d in the presence of magnetic fields. The binding energies of both D- singl et and triplet states are determined with high accuracy between 0 and 15 T. This constitutes the first conclusive evidence for the presence of D- trip let states in this system and enables existing calculations of the singlet and triplet binding energies to be tested over this wide range of field val ues.
