Updated results are presented from a study of low energy ..nu..-D/sub 2/ interactions using the ANL 12-Foot Bubble Chamber. These results for the quasi-elastic reaction ..nu..n ..-->.. ..mu../sup -/p and single pion production final states ..mu../sup -/..pi../sup +/p, ..mu../sup -/..pi../sup 0/p and ..mu../sup -/..pi../sup +/n are from a total exposure of 2.3 x 10/sup 18/ protons on target. The axial-vector form factor mass in quasi-elastic scattering, assuming a dipole form, is determined to be M/sub A/ = 0.98 +- 0.08 GeV. The single pion production channels are in good agreement with the predictions of the Adler model of weak pion production. In particular, the I = 1/2 pion-nucleon amplitude is substantial and relative to the I = 3/2, is determined to be (A/sub 1/2/)/(A/sub 3/2/) = 0.57 +- 0.06. 4 references.
