GCR flux decline during the last three centuries: extraterrestrial and terrestrial evidences
We have deduced the Galactic Cosmic Ray (GCR) annual mean spectra for the last 300 years (Bonino et al., 2001), using the open solar magnetic flux proposed by Solanki et al. (2000). From the GCR proton flux we have calculated the 44 T i (T1/2 =59.2 y) activity in small stony meteorites and we have c...
