Abstract A positron wave function incorporating the proper crystal symmetry is calculated for Al using the positron pseudopotential method. The positron ground state energy was also calculated and it was found to be in good agreement with the previous Wigner-Seitz calculations. The pseudopotential matrix elements are shown to be small and thus very accurate calculations can be performed using low order perturbation theory.
