Solar neutrinos observed by GALLEX at Gran Sasso

CRC Press eBooks (2018)

P. Anselmann W. Hampel G. Heusser J. Kiko T. Kirsten

152We have measured the rate of production of 71Ge from 71Ga by solar neutrinos. The target consists of 30.3 t of gallium in the form of 8.13 M aqueous gallium chloride solution (101 t), shielded by ≈ 3300 m water equivalent of standard rock in the Gran Sasso Underground Laboratory (Italy). In nearly one year of operation, 14 measurements of the production rate of 71Ge were carried out to give, after corrections for side reactions and other backgrounds, an average value of 83 +19 (sut.) ± 8 (syst.) SNU (1σ) due to solar neutrinos. This conclusion constitutes the first observation of solar pp neutrinos. Our result is consistent with the presence of the full pp neutrino flux expected according to the "standard solar model" together with a reduced flux of "B+7Be neutrinos as observed in the Homestake and Kamiokande experiments. Astrophysical reasons remain as a possible explanation of the solar neutrino problem. On the other hand, if the result is to be interpreted in terms of the MSW effect, it would fix neutrino masses and mixing angles within a very restncted range.

COSMIC RAY PRODUCED Ar$sup 37$ AND Ar$sup 39$ ACTIVITIES IN RECENTLY FALLEN METEORITES

R. J. Davis R.W. Stoenner O. A. Schaeffer

A review of methods for determining meteorite ages is presented. It is noted that the test of spatial variation that can be obtained from recentiy fallen meteorites is informntion that requires two years of space vehicle travel time to gather. Data obtained in the examination of five recent meteorites are included. Analysis of data leads to the conclusion that cosmic-ray intensity at several astronomical units from the sun is within 15% of the intensity at the earth's orbit. It is recommended that the accuracy of measurements be checked by the Ar/sup 37//Ar/sup 39/ ratio in iron meteorites. (J.R.D.)

Spallation of copper by 25-GeVC12ions and 28-GeV protons

Physical Review C (1976)

J. B. Cumming R.W. Stoenner P. E. Haustein

Relative yields of 35 products extending from $^{7}\mathbf{Be}\mathbf{to}$ $^{67}\mathrm{Ga}$ have been measured for the interaction of 25-GeV (2.1-GeV/amu) $^{12}\mathrm{C}$ ions with Cu. For purposes of comparison, cross sections of 48 nuclides produced by the irradiation of Cu with 28-GeV protons are also reported. The mass yield curve deduced for the 2.1-GeV/amu $^{12}\mathrm{C}$ ions is very similar to that reported for 0.28-GeV/amu $^{14}\mathrm{N}$, which implies that there is little energy dependence of target fragmentation cross sections in this energy range where meson production effects in nucleon-nucleon collisions become important. Charge dispersion curves for products with $37\ensuremath{\le}A\ensuremath{\le}64$ are the same within errors for $^{12}\mathrm{C}$ and protons. Compared with 28-GeV protons, the mass yield curve for $^{12}\mathrm{C}$ shows some favoring of products near the target (possibly due to increased secondary effects). Formation of light fragments such as $^{7}\mathrm{Be}$ and $^{24}\mathrm{Na}$ is significantly enhanced possibly due to highly damaging central collisions of the heavy ions. The results are discussed in terms of the concepts of limiting fragmentation and factorization.NUCLEAR REACTIONS Cu($^{12}\mathrm{C}$, spallation), $E=25$ GeV; measured relative $\ensuremath{\sigma}(A,Z)$, 35 products $^{7}\mathrm{B}\mathrm{e}\ensuremath{-}$ $^{67}\mathrm{Ga}$.
