From the nuclear physics point of view, we consider the antineutrino absorption on an electron capturing nuclear system leading to a fine resonance in the (N + 1, Z - 1) system, centered 50 keV above the highest excited state reached by the ordinary
electron capture. The deexcitation of this resonance will lead to a very characteristic [gamma] ray.
The
electron capture rates [U.sub.1] and [U.sub.2] represent
electron capture processes associated with capture cross-sections [[sigma].sup.0.sub.n] and [[sigma].sup.+.sub.n], and the rates [U.sub.3] and [U.sub.4] represent electron emission processes.
1) demonstrates that PCBs, as Aroclors and as evident by
electron capture detection, are not detectable in the oil.
Shape of the
electron capture to the continuum cusps for H, [H.sub.2], and He targets.
Gas chromatography (GC) with
electron capture detection provides good sensitivity but lacks specificity (20-22).
After a 5-6 h incubation, [N.sub.2]O production was quantified using a Shimadzu gas chromatograph with an
electron capture detector.
These first detectors worked on a technology known as
electron capture, which is based on the principle that all explosives have a certain chemical nature (electronegative).
However, metallic As precipitates are neutral and
electron capture might not be likely.
More than a decade ago, theorists predicted that the probability of
electron capture would increase significantly if such collisions took place in an intense laser beam of an appropriate wavelength.
