  The calculation results of solar neutrino capture cross-section on the
$^{76}Ge$ nucleus are presented. The charge-exchange strength function $S(E)$
was obtained from the experiment data in the $ ^{76}Ge(^{3}He, t)^{76}As $
reaction. The calculation includes the effect of the resonant structure of the
strength function $S(E)$ on the calculated cross section $\sigma(E_{\nu})$. It
is shown that only the giant Gamow-Teller resonance contributes about 20%, and
an even greater contribution is made by excited states located lower in the
continuous part of the spectrum. These contributions should be taken into
account in the calculation of background events in experiments on double beta
decay of the GERDA type (for example LEGEND).
