X-ray spectra of hercules x-1. 3: pulse phase dependence in high energy continuum. [less than or equal to 20 KeV]

Technical Report ·
OSTI ID:6508223
; ; ; ;
Pulse phase-dependent spectral changes in the high energy (less than 20 keV) continuum of Hercules X-1 were observed. Cyclotron absorption of underlying continua can reproduce the observed angular dependence in the high-energy cutoff. Implications of this model, which include the possibility of determining the angular separation between the line of sight and the neutron star magnetic field if the absorbing electron spectrum is known, are discussed.
