Monopole-antimonopole pairs of fixed angular momentum in superfluid 3He-A

We discuss the possibility of the formation in superfluid 3He-A of monopole-antimonopole pairs that carry angular momentum along the axis, especially in the context of situations characterized by a fixed value of the bulk angular momentum. Two rather different structures are considered, one which is likely to occur for large angular velocity (angular momentum), and another which could appear for low angular velocity
