Abstract
A study is made of the lattice constructed from nonsingular vortices in superfluid3He-A in a strong magnetic field. In the presence of a magnetic field the vortex texture loses axial symmetry, and the ľ vector outside the vortex core is nearly uniform and is directed perpendicular to the rotation axis. It is shown that the vortex lattice is spontaneously distorted and its energy depends on the orientation of the unit cell relative to the direction of the uniform ľ vector outside the core. It is also shown that the orientation of the lattice changes when the tilting angle of the magnetic field from the rotation axis is changed. The optimum orientation angle of the distorted vortex lattice is calculated as a function of the tilting angle.
