Sažetak
This paper presents an analysis of angular distribution of target fragments in lepton nucleus interactions in terms of scaled factorial moments (SFMs) in one-dimensional space. A power-law type behaviour of normalised scaled factorial moments, popularly known as 'intermittency', is expressed with a decreasing phase space. Our data of target fragments reveal a similar type of increase in SFMs with decreasing bin width of the angular distribution in muon-nucleus interactions at (420±45) GeV. The new observation contradicts the existing concept of the evaporation model that the statistical equilibrium is reached before the emission of fragmented particles from residual target nuclei at high-energy nuclear interactions.
