It is shown that there are two solutions for two fixed width resonances. Analytical relation between different solutions is derived. Numeric experiments for fixed width three and four resonances, and for model energy-dependent width two resonances confirm ambiguity of the resonances parameters determination.43 pages, 15 tables, 16 figuresHigh Energy Physics - PhenomenologyHigh Energy Physics - ExperimentData Analysis, Statistics and Probabilitytext
