A solution to these problems is proposed based on the method of fluctuation reduction (MFR). This method assumes the universality of the development of cascades formed by particles of the same energy and charge. It is shown that the correlation curves used in MFR fluctuate significantly less than the cascade curves. In this regard, the use of correlation curves allows one to significantly increase the accuracy of determining energy in individual events.

The problem of finding weak wave modes against the background of a spheron is reduced to solving a second-order differential equation. The solution is sought by expanding into an asymptotic series in inverse powers of the radius in a spherical coordinate system. A recurrent formula for the series is obtained.
