Theoretical predictions
The nuclear reactions in the Sun generate a numerous amount of electron neutrinos. While the total number of neutrinos can be calculated very accurately, their energy spectrum contains more uncertainties. The following picture shows the principal energy producing reaction chains:
Below is shown the neutrino spectrum calculated by
John Bahcall and Pinsonneault.
The next table shows the predictions for the solar neutrino experiments:
| Experiment | BP 00 | BP 98 | Bahcall 95 | Turk-Chiéze | Dar-Shaviv 95 | Proffitt94 | |
|---|---|---|---|---|---|---|---|
| Chlorine | 7.6 +1.3-1.1 | 7.7 +1.2-1.0 | 9.5 ± 1.4 | 6.4 ± 1.4 | 4.1 ± 1.2 | 8.9 ± 1.1 | |
| Kamiokande | 5.05 (1.00 + +0.20-0.16) | 5.2 +1.0-0.7 | 6.6 ± 1.1 | 4.4 ± 1.1 | 2.49 | 6.4 ± 0.9 | |
| Gallium | 128 +9-7 | 129 +8-6 | 137 ± 8 | 122 ± 7 | 115 ± 6 | 136 ± 7 |
The contribution of different reaction chains is beautifully visualised
in the picture below,
