Abstract
The hydrogen molecules embedded in superfluid helium as a gas jet
are shown to form long thin filaments. These filaments survived under
helium transition to a normal phase demonstrating their conjugated entity.
The concentration of an impurity in the core of vortex may be the
mechanism of the impurity coalescence providing a cotton-like structure of
a condensate obtained by the impurities contained gas helium jet introduction
to He-II.
