Abstract
THE pulsar NP 0532, located in the Crab Nebula, emits pulses of light1,2 with the same period as the radio emission. The polarization2 of the light suggests an origin in the synchrotron radiation process, indicating the presence of high-energy electrons. In this article the gamma radiation resulting from various processes associated with these electrons is calculated. While gamma radiation from NP 0532 has not been observed experimentally, there are observations of gamma radiation from the Crab Nebula3–8 that give upper limits on gamma emission from NP 0532. My calculations and these upper limits lead to the conclusion that the magnetic field H near the light-emitting region of NP 0532 is 102 ≲ H ≲ 104 G.
