Heidelberg-Moscow Collaboration experimental data [1-4] with the claim forthe observation of the neutrinoless double beta-decay of Ge-76 has beencarefully analyzed. The analysis gave an evidence that the observed 2039 kevline in the full spectrum was produced by overlapping of three unresolvedpeaks: ~2035.5 kev, ~2037.5 kev and ~2039.5 kev. It was indicated that the2035.5 kev and 2039.5 kev peaks were produced by the double-coincidences ofgamma-quanta in the detectors. Existence of the two background gamma-peaks at~2035.5 kev and ~2039.5 kev was confirmed by an analysis of the backgroundmeasurements with low-background Ge detectors with an active shielding [5-7].The 2037.5 kev line could be the expected 2{\beta}0{\nu}-decay transition of76Ge according to the results of the improved pulse-shape analysis. Position ofthe line, 2037.56+/-0.56(stat)+/-1.2(syst) kev [4], was slightly below theexpected, E2{\beta}=2039.0+/-0.05 kev [8], but still within a limit for poorstatistics. The most accurate value of its intensity was extracted from the51.39 kg \cdot y data with PSA: number of events 12.4+/-3.7 and T1/2=1.98 \cdot1025 years [2,3].
