2 show the correspondence of these tropospheric levels with the main equipotential surfaces [37; 2] = 7.5 km, [38; [infinity]] = 12 km and [38; 2] = 20 km of the fundamental field F, calibrated on the electron wavelength.
2 show the correspondence of the PBL features with the main equipotential surfaces [35; [infinity]] = 600 m, [36; [infinity]] = 1600 m and [37; [infinity]] = 4.5 km of the fundamental field F, calibrated on the electron wavelength. It is noticeable that in 1992 Hess [24] already reviewed scaling aspects of the boundary layer.
2 show the correspondence of the mesopause with the main equipotential surface [40; [infinity]] = 90 km of the fundamental field F, calibrated on the electron wavelength.
2 show the correspondence of the thermopause with the main equipotential surface [42; [infinity]] = 650 km of the fundamental field F, calibrated on the electron wavelength.
While the outer belt maximum corresponds with the main equipotential surface [45; [infinity]] = 13000 km of the fundamental field F, calibrated on the electron wavelength, the inner belt maximum corresponds with the equipotential surface [43; 2] = 3000 km that is the main equipotential surface [51; [infinity]] of the fundamental field F, calibrated on the proton wavelength.
The precision is in the order of 1/3000 of the electron wavelength, which is 15 times higher than the best precision (the order of 1/200 of the electron wavelength) obtained in RIKEN using a conventional magnetic observation technique.
When the well width is approximately equal to an integer or half-integer multiple of the electron wavelength, a resonance condition occurs.
In their theoretical analysis, Gaylord and Brennan consider a filter consisting of nine layers, each layer a quarter or a half of the electron wavelength in thickness.
To see quantum size effects, says Avouris, scientists must look at materials on approximately the same scale as the electron wavelengths. The smaller the terrace, the shorter the wavelengths and the greater the energy and frequency of the electrons trapped there.
However, this conclusion cannot be made based on the estimation of their masses only, but requires an additional estimation of their radii, which should correspond with vacant positions in the fundamental fractal F (1) that is calibrated by the proton and electron wavelengths.
