Description
At the previous International conference on particle physics and astrophysics (2015) we presented the report ''Estimation of reliability of linear point structures revealed in two-dimensional distributions of experimental data" [O.V. Falomkina, Yu. V. Pyatkov, et al., Estimation of reliability of linear point structures revealed in two-dimensional distributions of experimental data.// JPCS — V. 675., P. 042001 (2016).] where we discussed the results of the solution of the problem of estimation of statistical reliability of linear point structures, obtained from the experiments at the FOBOS spectrometer [H-G.Ortlepp, et al., NIM A 403 (1998) 65] dedicated to study of the spontaneous fission of the 248Cm and 252Cf nuclei in the mass correlation distribution of fission fragments. These new unusual structures bounded by magic clusters were interpreted as a manifestation of a new exotic decay called collinear cluster tri-partition (CCT)[D.V. Kamanin, Yu. V. Pyatkov, "Clusters in Nuclei - Vol.3" ed. by C. Beck, Lecture Notes in Physics 875, pp. 183-246 (2013)]. The reliability of these structures was estimated on the basis of methods of morphological image analysis [Pyt’ev Yu.P. Morphological Image Analysis. — Pattern Recognition and Image Analysis. V.3. No 1. 1993, pp. 19-28.].
To improve the quality of revealing and further estimation of linear structures statistical reliability in the mass correlation distribution of fission fragments mathematically we used the formalism of oblique projecting [Yu.P. Pytyev. Oblique Projectors and Relative Forms in Image Morphology //Computational Mathematics and Mathematical Physics, 2013, V. 53, No. 12, pp. 1916-1937]. At this report we compare the orthogonal and oblique projectors and discuss the obtained results.
