  A correction of the neutrinoless 2\b{eta}-decay model was proposed which
predicted a shift of the 2\b{eta}0{\nu}-signal from the Q value (2\b{eta}-decay
energy). The shifts were calculated for 76Ge (\D{elta}E=-2.6 keV), 100Mo
(\D{elta}E=-4.7 keV), 130Te (\D{elta}E=-3.7 keV). The calculations for 76Ge
were in agreement with H-M results. A reanalysis of the published Quoricino
data (a search for a 2\b{eta}0{\nu}-decay of 130Te) was performed. It indicated
a presence of a signal at E = 2523.5 keV \a{pprox} Q(130Te)-3.7 keV. It could
be attributed to the 130Te neutrinoless 2\b{eta}-decay with T1/2 =
(5.7+-2.3)10^23 y. A comparison of the H-M and Quoricino data has strongly
supported the experimental observation of the 2\b{eta}0{\nu}-decay process and
a validity of the proposed correction.
