✦ Synopsis

The stability region of the helical textures in 3He-A in the vs-H phase diagram is theoretically determined. Here Vs is the supe~_ ow velocity and H (live) is the external magnetic field. The pitch of the helix k-that minimizes the Gibbs free energy and the corresponding inclination angles of ! and d are determined numerically as functions of vs and H. The NMR frequencies (two longitudinal and four transverse frequencies) associated with the helical texture are obtained.
