Obtained sum rules have good stability and correspond to pentaquark mass $m_θ$=1.54 $GeV$ at the appropriate choice of continuum threshold. Also the features of the sum rules for 2-point correlator with 5-quark currents are studied. This features should be taken into account to obtain sum rules correctly.14 pages, 3fig, misprintrs are corrected,notation in fig 2,3 are correctedHigh Energy Physics - Phenomenologytext
