Abstract: (Elsevier)

We construct nonperturbative solutions for the discretized Green-Schwarz superstring in one dimension. This is compared with a modification of the WKB series such that supersymmetry is preserved. The logarithmic divergences due to massless modes appear again, as in the bosonic string case. However, the density of states is different from the bosonic string theory, giving rise to a new series. We comment on the multicritical cases that could arise.
