Study of the Diffuse X-Ray Background Radiation in the Spectral Range from 44 to 100 A and the Determination of the Polarization of the X-Ray Emission from the Crab Nebula.

Abstract

A system for the detection of ultra-soft x rays (0.100 - 0.300 keV) employing grazing-incidence optics and thin window gas-flow proportional counters has been developed. This system is especially suited to photometric measurements of low-energy cosmic x-ray intensities. A rocket-borne x-ray polarimeter was flown to search for polarization in Taurus X-1. Although a result consistent with zero polarization was obtained, the statistics were such that x-ray polarization comparable in magnitude and direction to that of radio and optical continuum emission cannot be excluded.
