✦ Synopsis
We consider a hypothesis that nondissipating wave-bound beam structures may be created in plasma due to interaction between energetic charged particles and undamped waves. This hypothesis, if correct, might account for several phenomena observed in the Sun.
For instance, on entering the atmosphere and then decaying, the structures may lead to flares.
Furthermore~ the idea offers propitious prospectm of solving the well-known problem of the solar neutrino deficit. In addition~ a relation between phenomena occuring within the Sun's core and those on its surface becomes possible.
Recently has reviewed the results of a long-standing study of the solar neutrino flux and its possible temporal variations.
The observations seem to show that the solar neutrino flux is in anticorrelation with the sunspot number (see also discussions by Gough~ 1988, and Bathe, 1989). An explanation has been proposed by Marciano (198S), Akhmedov (1988), and. Their model requires the simultaneous presence of neutrino flavour mixing and a magnetic (or transition) moment. In this paper, we discuss an alternative hypothesis.
Can physical phenomena observed on the solar surface be related to those occuring deep in the interior? A relation might exist if collisionlessly moving wave-bound beam structures were created within the ~un.
An example of ~ollisionlessly moving charged particles is Cooper pairs created in low-temperature semiconductors . In this case, attraction between electrons with opposite spins and momenta arises in consequence of their interaction with the ion lattice. The Cooper pair is not destroyed, and its motion is collisionless if its binding energy is larger than the energy released by collisions with other particles.
Of course, in the case of a high-temperature plasma, the formation of similar nondissipating structures is highly problematic. First~ the possibility of sufficiently strong attraction between two equal charges moving through the plasma should be verified. ~econd, the conditions for the formation of a Bose-condensate of paired fermions must be
