We investigate the possibility of approximation
isometrical operators in Hilbert space.
Further we give the criterion of innerness of quasifree
automorphisms of hyperfinfite factors of
type and type generated by the representations of
the algebra of canonical anticommutation relations (CAR).
The results are used to describe cocycle conjugacy classes of
quasifree shifts on hyperfinite factors of .
