Path length distribution of cosmic rays from pulsar nebula complexes
- 20 Downloads
Particles accelerated in the vicinity of pulsars have to traverse the nebular matter surrounding pulsars. Using the variation of pulsar luminosity and nebular expansion, the path length distribution for the particle radiation is deduced and compared with that obtained from experimental observation. It is found that a significant amount of matter traversed by cosmic rays can be in the source itself; but it is not possible to simultaneously account for the production of secondary electrons and secondary nuclei with the same set of parameters.
