Resonant soft X-ray diffraction - in extremis.
The use of softer-energy X-rays produced by synchrotron radiation for diffraction is an area of current interest. In this paper, experiments exploiting resonant scattering at the L absorption edges of 3d transition metal elements are reported. Such energies, typically 500-1000 eV, are at the extreme limit of soft X-ray diffraction where absorption effects are so severe that the sample and diffr...
متن کاملGrace
whence she had come nor whither she was bound, for she had no record of any kind with her. When she was questioned her vocabulary seemed to consist solely of head shakings and a few utterly unintelligible syllables. It is not recorded how Grace happened to be thrust into a second grade that first day. But it was the second grade teacher who began to complain, a few days later, of "that little n...
متن کاملMatter in extremis: Ultrarelativistic nuclear collisions at RHIC
We review the physics of nuclear matter at high energy density and the experimental search for the Quark-Gluon Plasma at the Relativistic Heavy Ion Collider (RHIC). The data obtained in the first three years of the RHIC physics program provide several lines of evidence that a novel state of matter has been created in the most violent, head-on collisions of Au nuclei at √ s = 200 GeV. Jet quench...
متن کاملGerald Grace
The death of Mr. Gerald Grace took place in South Africa as the result of a singularly tragic incident on Sept. 17th. For some time the Witwatersrand had been terrorised by a band of desperadoes. Mr. Grace was travelling on the Witwatersrand reef in a motor-car resembling that in which the gang was believed to be escaping. The police challenged the car, but, according to the account in the Rand...
متن کاملA Message From Dr Grace Dammann about States of Grace
P eople have asked me how I decided to participate in the film States of Grace. When we started, I'd been in the hospital for well over a year, and I thought, " Of course this makes sense. " My attitude toward pretty much everything that comes my way in life is to just say " yes " and pick up the pieces. So my attitude was Just say " yes " because you've had an incredible experience—both becaus...
