Study of the θ point by enumeration of self-avoiding walks on the triangular lattice

The author reports series expansion analyses of self-avoiding walks with nearest neighbour bond interactions. The estimates 2 nu t =1.07+or-0.05 and phi =0.64+or-0.05 for the correlation and crossover exponents at the theta point were obtained by examining the number of walks and the end-to-end distance data up to 16 steps on the triangular lattice.
