DESCRIPTION:Speakers: Andrei Vyborov (MIPT)\nThe calculations of the captu
 re cross section of solar neutrinos σ (E) by the 76Ge nucleus are present
 ed. The calculations used experimental data on the strength function S (E)
  obtained in the charge-exchange reaction of 76Ge (3He\, t) 76As. The effe
 ct of the resonant structure of the strength function S (E) on the calcula
 ted cross section σ (E) was investigated. It is shown that only a giant G
 amow-Teller resonance contributes about 20%\, and an even greater contribu
 tion is made by excitations located lower in the continuous part of the sp
 ectrum. These contributions should be taken into account in the calculatio
 n of background events in experiments on double beta decay of the GERDA ty
 pe (LEGEND).\n\nhttps://indico.particle.mephi.ru/event/22/contributions/11
