Plasma pinch as a source of cosmic rays
Vlasov V. P. , Zhdanov S. K., Trubnikov B. A.
The hypothesis that galactic cosmic rays are produced in cosmic plasma pinches leads to an accelerated-particle spectrum dN/dE~E ~ v with an index ν = 1 + лД, which is approximately equal to the observed value v0 = 2.7. The hypothesis therefore looks extremely plausible.
