| Description | The reported e(sup +/-) annihilation line from the Crab pulsar has three remarkable properties. It is very strong (approximately 10(exp 40)e(sup +/-) annhilations/sec.), red shifted (by about 70 KeV relative to mc(exp 2) = 511 KeV), and very narrow (width approximately equals 10 KeV). The e(sup +/-) annihilation did not occur near the star in polar cap accelerator models so that the redshift, suggestive in its magnitude of a gravitational redshift from annihilation near the stellar surface, did not have an explanation. Therefore, concentration was placed on e(sup +/-) production from outer-magnetosphere accelerator models. |
