the absolute neutrino-mass scale remains unknown. Here we report the upper limits on effective electron anti-neutrino mass,mν, from the second physics run of the Karlsruhe Tritium Neutrino experiment. In this experiment,mνis probed via a high-precision measurement of the tritiumβ-...
An attempt is made to study the effect of a quantizing magnetic field on the effective electron mass in degenerate n -type narrow-gap semiconductors at low... AN Chakravarti,AK Chowdhury,KP Ghatak,... - 《Applied Physics》 被引量: 30发表: 1981年 Influence of Magnetic Quantization on the ...
The 70 eV electron ionization (EI) mass spectra were recorded for eight norbornane/ene-fused 2- N -phenyl-iminoperhydro-1,3-oxazines, and the fragmentation patterns were studied by metastable ion analysis and exact mass measurement. Whereas the stereoisomeric unsaturated compounds could not be ...
The use of a circuit with a relatively low impedance (6 \Omega) and a small interelectrode gap (\sim1~mm) made it possible to obtain a relatively high discharge current (\sim1~kA) at an initial voltage of 10–15 kV. Therefore, an electron beam consisting of a train of pulses with ...
Electron impact mass spectrometry (EI-MS) involves the bombardment of the vaporized metabolite by high-energy electrons (0–100eV), producing a molecular radical cation (M+·) having a mass equivalent to the molecular weight of the compound. ...

Its self-organization can be reconstituted in vitro26 and the underlying mechanism has been probed by various techniques such as SPT13, high-speed atomic force microscopy27, nuclear-magnetic resonance28, electron microscopy29, plasmonic nanosensors30 and mutational analysis31,32. Despite this intense ...
Search for the electron-positron decay of an axionlike particle from a 590 MeV proton beam dump A search was made for the decay of a light neutral particle into an e+e--pair behind the dump of the PSI (formerly SIN) 590 MeV proton beam. The detector c... H Faissner,W Heinrigs,A...
