Gamma rays with energies greater than 7 TeV from the Crab pulsar/nebula have been observed at large zenith angles, using the Imaging Atmospheric Technique from Woomera, South Australia. CANGAROO data taken in 1992, 1993 and 1995 indicate that the energy spectrum extends up to at least 50 TeV...
The detection of gamma rays of energy greater than 300 GeV from the BL Lacertae object Mrk 501 demonstrates that extragalactic TeV emission is not unique to Mrk 421. During 66 hr of observations between 1995 March and July we measured an average flux of 8.1 ± 1.4 × 10 -12 cm -2 s ...
The authors report the first measurement of high-energy gamma rays with a low-temperature calorimeter. The detector is a crystal of about 10.7 gm operated at a temperature of about 30 mK. The thermal pulses produced by gamma rays are detected and measured by a thermistor in thermal contact wi...
gamma spectraDURING the past ten years the development of semiconductors for the detection of gamma rays has been proceeding at an accelerating pace, so that lithium drifted silicon detectors, as well as lithium drifted germanium detectors and undrifted germanium detector materials, are now ...
A.systeme of detection of neutrons and or of the gamma rays having a large surface of the reception of the radiation to which we shall now describe the product of the photons in the drawings, which produces a scintillation photons which are captured in the optical fibers forming the driver....

In NPC, scattering of deuterium is on par with carbon, nitrogen, and oxygen, increasing the ability to locate proton positions for the entire enzyme. An additional advantage is that neutrons, unlike X-rays, do not alter the electronic state of metals17. The capability of proton visualization ...
DNA double-strand breaks (DSBs) are the most lethal form of damage to cells from irradiation. γ-H2AX (phosphorylated form of H2AX histone variant) has become one of the most reliable and sensitive biomarkers of DNA DSBs. However, the γ-H2AX foci assay
