  The T-noninvariant transverse polarization of neutrons is considered for muon
capture by a 6-Li nucleus with decay into a quasistationary 2+ state of the
three particle alpha+n+n continuum. This polarization is orthogonal to the
plane spanned by the polarization axis of the initial mesic atom and the
neutron momentum. The situation in which neutrons that are emitted in the plane
orthogonal to the axis of the mesic-atom polarization and which have oppositely
directed momenta equal in magnitude are selected is analyzed. The wave function
of the final state is constructed by using the method of hyperspherical
harmonics. In the approximation of the allowed Gamow-Teller transition 1+ to
2+, this neutron polarization is expressed in terms of the T-noninvariant
relative phase of reduced matrix elements for transitions from the 6-Li ground
state to various final-state configurations.
