Spectroscopy of Solar Neutrinos with Borexino
The results of all solar neutrino experiments carried out so far are shown in Tab l (the gallium experiments Gallex and Sage are taken together). For comparison the range of predictions of several Standard Solar Models (SSM)    is listed for each type of experiment together with the calculated contributions of the strongest solar neutrino branches. A basic analysis shows that the result of Kamiokande , which is only sensitive to the high energetic and less accurately predicted 8B-neutrinos, is in the range of predicted values. That means, depending on the underlying SSM, there is a deficit of neutrinos or not. Combining the Kamiokande result with the data of the radiochemical Homestake-experiment  the derived flux for the 7Be-neutrinos seems to be strongly suppressed for all SSM’s.
