The distinction between X-rays and gamma rays is not so simple and has changed in recent decades. According to the currently valid definition, X-rays are emitted by electrons outside the nucleus, whilegamma rays are emitted by the nucleus. For X-rays generated...
There are "soft" and "hard" X-rays.Soft X-rays are between ultraviolet and gamma rays on the electromagnetic spectrum Hard X-rays are in the same region as gamma raysGamma RaysGamma rays have the highest energy , highest frequency and shortest wavelength in the electromagnetic spectrum....

Detections of γ-rays1 and X-rays2,3 from Supernova 1987A, together with its exponential light curve4, have dramatically confirmed theoretical predictions made two decades ago5–7. We discuss what these observations, in August and September 1987, can alr

Search for ultrahigh-energy gamma rays from SN1987A The Japanese X-ray astronomy satellite Ginga observed X-rays from the region of SN1987A. In many model calculations, the hard component of the X-rays has been interpreted by the Compton degradation of line gamma-rays from the decay of (5...
CHAPTER 1 Physics of Gamma and X-rays DEFINITION Gamma and X-rays are highly penetrating electromagnetic radia tions characterized by wave lengths in the range of 10" ^-10" ^ ^ cm and, consequently, by frequencies ranging from 10^"^ to 10^^ sec" ^ Fig.l shows the wave length and...
