Two different types of X-ray polarimeters were used in a sounding rocket to search for X-ray polarization of the Crab Nebula. Polarization was detected at a statistical confidence level of 99.7 percent. If the X-ray polarization is assumed to be independent of energy, the results of this and a previous experiment lead to a polarization of (15.4 + 5.2) percent at a position angle of 156 + 10 . This result confirms the synchrotron model for X-ray emission from the Crab Nebula.
Novick et al. (1972) studied this question.
