Ukraine Kharkov Physics and Technology Institute of Physics for the first time managed to capture the structure of the atom the electron levels. Photos featured a detailed comparison of the incremental carbon atom is formed by electron clouds.
This is the first time ever scientists have managed to take a look at the internal structure of the atom. Mathematically the internal structure of the particles described by experts still early eighties, but was able to use imaging technology is only now.
According to quantum mechanics as allegations that the electron does not exist as a tangible point however orbits around the nucleus of an atom, electrons form a cloud which is still known orbital title. The presence of an electron at a point can be described only. Pictured visible spills the blue sphere represents the two electrons and their orbital configurations of carbon atoms. These images confirm in chemistry and physics textbooks, the information provided ie in accordance with generally accepted quantum mechanics assumptions.
California Stanford University (USA), a physics professor David Goldhaber-Gordon This scientific attainment is called impressive. One of the advantages of this method is that it provides tangible results. We as a people we love to see real images such as photos and information we’ve learned a lot faster and easier especially for those people who go into the less physical subtleties.
These photographs capture the researchers used an electron microscope field emission (called field-emission electron microscope FEEM). They are in a vacuum chamber instead posted a rigid chain of ten carbon atoms and the sample is affected by the 425 volts. Link at the top of carbon atom electrons which crashed into the sample surrounding the nucleus of a phosphorus screen restored the electron cloud surrounding the picture. Field emission electron microscopes are the main research tool since the fourth decade. They went deep into the researchers continually growing smaller objects structure. Until now these microscopes could only see the atomic structure of matter.
The oblique tip of the sample is directed to a phosphorus screen vacuum chamber the greater the resultant image resolution explains one of its authors Igor Mikhailovskij. In recent years, physicists learned to manipulate the carbon chain. When the sample peak is just one atom wide and a microscope can see atomic orbitals. Kharkiv scientists are the first who succeeded in capturing the real one-atom electron cloud pictures, thus allowing the eyes to look at quantum mechanics assumptions.
While similar studies have been attempted using scanning tunneling microscopy, it is always a good alternative methods says Goldhaber-Gordon. Sometimes what is unclear in one respect, it is fully understood the application of other alternative approaches. Each of them brings us closer towards a real understanding. Goldhaber-Gordon also believes that the method in the future may not be very popular because it requires a specific atomic structure of the sample. The current method is much more important in the sense that it allows a direct insight into the laws of quantum mechanics rather than exploring new materials properties. However, this may change if the Ukrainian scientists will be able to refine the method consider a professional.
