Beta-delayed alpha-particle emission from 118, 120 Cs

Systematic trends in beta-delayed particle emitting nuclei: The case of βpα emission from 21Mg

Microscopic description of the beta delayed deuteron emission from 6He.

The beta delayed deuteron emission from 6He is studied in a dynamical microscopic cluster model. This model gives a reasonably good description for all the subsystems of 6He and 6Li in a coherent way, without any free parameter. The beta decay transition probability to the 6Li ground state is underestimated by a few percents. The theoretical beta delayed deuteron spectrum is close to experiment...

Alpha particle emission from reference glass surfaces implanted with 210Po.

Implanted long-lived radon decay products in glass surfaces have been used as a measure of past radon exposure in homes. Special track-etch devices (so-called 'retro-detectors') attached to the glass surface, have the ability to specifically measure the implanted activity of 210Po in situ. Calibrating these devices for 210Po is fairly straightforward, but the retro-detectors are also sensitive ...

Information Flow Investigations (CMU-CS-13-118)

Information-flow analysis has largely ignored the setting where the analyst has neither control over nor a complete model of the analyzed system. We formalize such limited information flow investigations and study it in three domains: (1) the determination of what third-party web trackers do with the information they collect, (2) the identification of copyright violators, and (3) the detection ...

X-ray Emission from the Radio Jet in 3c 120

We report the discovery of X-ray emission from a radio knot at a projected distance of 25′′ from the nucleus of the Seyfert galaxy, 3C 120. The data were obtained with the ROSAT High Resolution Imager (HRI). Optical upper limits for the knot preclude a simple power law extension of the radio spectrum and we calculate some of the physical parameters for thermal bremsstrahlung and synchrotron sel...
