In3He-A there exist two helical textures: one withl almost aligned with the flow for small magnetic fields compared to the current (roughly\(h \lesssim \sqrt {20{\text{j}}} \lesssim 1.2\) in dipole units) and another withl almost orthogonal to the flow for larger fields [h⩾(40/7)1/2j⩽1]. Here we calculate the ratio of the decay rates of the second current, namely the wide-angle helix, to smaller or larger values of the opening angle, via quadratic fluctuations around an extremal excursion from equilibrium.
