چکیده انگلیسی
The accuracy of the routine investigations by the modern gas-phase electron diffraction method is no more than 0.1%. The full error of parameters determination consists of several contributions including the scale error and the errors in sector function. For correction of the scale error and estimation of the sector function, the gas standard method is used in gas electron diffraction. We have developed the new method for simultaneous determination of the electron wavelength and the sector function from the intensity curves of the gas standards. The new method allows to achieve the electron wavelength precision of about 0.02-0.05%. The distinguishing feature of the new method is the use of several intensity curves for determination of the sector function, resulting in an increase of the reliability of the sector function determination. The additional information from alternative determinations of sector function can be also used for regularization.
