We estimate that gamma rays would be degraded at spinars, too, at energies > 1 GeV.

The error region of the unidentified source 2CG195 + 04 (Geminga) is studied at other wavelengths in greatest detail. This search for a counterpart is summarized, showing the possibili

Preface, in Patras, August 19, 1982. Roughly one hundred scientists attended this meeting, the discussions were lively — sometimes heated — and the original time span allocated to the meeting was a result, comfortably exceeded by about 50%.

The complex problem of cosmic ray transport in random electromagnetic fields is reduced to three cases which should be sufficient for practical purposes. As far as diffusive acceleration is concer

Acceleration and Transport Processes: Verification and Observations,r modulation of galactic cosmic rays and shock acceleration processes on the solar wind are examined and observational tests are summarized. It is concluded that the basic diffusive transport equation is a useful approximation in situations like the solar wind, where turbulent scattering by magnetic
