We report the first observation of s-like excited states of a double acceptor in a semiconductor. Measurements on two different liquid encapsulated Czochralski GaAs samples containing the 78-meV acceptor showed the first s-like excited state of this level to be split. We present a simple model which predicts the 1s¹2s¹ excited state of a double acceptor in GaAs to be split by 4.0 meV, in good agreement with our observed value of 2.6 meV
