Thanks to the detailed understanding of all relevant sources of background signals it became clear that 126 observed events in the data were indeed caused by the double electron capture

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
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.
The gas chromatograph with two electron capture
detectors (ECD) is to be used for the determination
