A double quantum physics experiment, and one of the greatest mystery of all is the fact that electrons behave differently than attempt to directly observe. Double slit through the hurdle of moving electrons generate interferentismustri, but the experiment by adding a detector which monitors a strange slit the electron goes through, bulk tube the pattern disappears. When working with a new detector to test a modified version of a double, bulk tube a study conducted by Italian scientists found a clue to why electrons behave differently observation event.
When the gap was placed on the filter to the right, were scattered electrons are more likely to be well behaved inelastically spherical waves. Exposed bulk tube gone through the slits were scattered electrons are more likely behaved bulk tube elastically and cylindrical waves. Two different wave phase relationship was not, therefore, even if the electrons are passed through both slits, they could not cause interference pattern.

One of the most famous quantum physics experiment bulk tube demonstrates a double test kvantmaailma a huge difference in the world. If two slots hurdle makroskaalas shoot through objects, moving them directly through the slot and leave the obstacle to the wall behind the two straight lines. If makroskaalas objects through use, however, the electrons do not fall on the wall, but not the two straight lines but instead a multi-line bulk tube interferentsmuster. To interferentsmuster also arises when electrons shoot one at a time, the experiment seems to suggest that, like an electron moving through the two holes at a time and interferes with itself, as if he would wave rather than a particle, writes Physorg.com.
Another unusual part of a double test is the fact that the electrons end up causing the interference, when researchers put one slit edge detector to monitor which of the two slits the electron actually goes through. Under these conditions, causing the electrons to the wall but just two straight lines, bulk tube as though they were objects makroskaalas.
Through the years, researchers have demonstrated a double test different versions. A new study by the Italian physicists Frabboni Stefano, Gian Carlo and Giulio Pozzi Gazzada transmission-elektronmikriskoopi using another version of this test.
,, We tried a couple bulk tube of the prior year to take advantage of their experience by transmission electron microscopy, and focused ion beam test preparation, but we realized that some of the basic tests were related to some of the mysteries of quantum mechanics, "explained Frabboni.
First, the researchers focused ion beam cut through bulk tube the obstruction, two slit. Is then modified by one of them, by covering with a low atomic number material with a multilayer filter, to thereby obtain a detector which detected, which one electron passed through the slit.
Although (fired one at a time), the electrons still got to go through the filter, caused by inelastic scattering bulk tube of electrons filter more. Wanders inelastic electron localized at the slit covered, bulk tube and acts like a spherical wave passing through the slit. Exposed through the slit the electron dissipates more likely to behave elastically, and passing through the slit of the cylindrical waves. Spherical and cylindrical bulk tube wave phases are not in any relation to each other, which means that even when an electron passes through both of the slots, can not be generated waves of two different wall interferentsmustrit cause.
Also, the researchers found that the thickness of the filter put in place interferentsimustri out of sight: the thicker the filter, bulk tube the greater the probability of dispersal inelastic - so there was less interfereerumist. The filter could also be prepared in a thick layer, the interference disappeared bulk tube almost completely.
If ,, electron inelastically dissipated, it is localized - the wave function collapsed, and after mõõtmisakti it spreads to the interaction bulk tube of the field like a spherical wave, and had no relationship with other phases or not elastic bulk tube scattered electrons, "described Frabboni inelastic scattering.
The second, independent experiment, the researchers covered the resistance bulk tube of the two slots, to see if the two spherical waves generated by the interference on the wall. It was found that low-intensity inelastic did not have any bars. Low-intensity bands arose again, however, were obtained when the elastic image.
In summary, the results seem to be saying that the electron scattering is determined by the type of trail obstacle to the wall behind, and that there is a single slit at the detector can change the type of scattering. Physicists have explained that the elastically scattered electrons, causing interferentsimustri, non-haj
