All Tables

Table 1: This table indicates the radius $r_{\rm lim}$ inside which a given fraction $f(r_{\rm lim})\equiv {\cal P}(r_{\rm s} < r_{\rm lim}\vert O )$ of cosmic rays reaching the center were emitted from, for several L and in the case of the infinite disk and R=20 kpc.
Table 2: This table indicates the radius inside which a given fraction $f(r_{\rm lim})$ of secondary cosmic rays reaching the center were emitted from, for several L and in the case of a disk of radius R=20 kpc. The last line shows that for small L, the effect of the side boundary is completely negligible.
Table 4: This table indicates the radius of several f-surfaces, for several values of L, $V_{\rm c}$ and $\sigma _{\rm inel}$ . We have introduced $L_{10}\equiv L/10$ kpc, $V_{10} \equiv V_{\rm c}/10$ km s^-1 and $\sigma _{100}\equiv \sigma /100$ mb.
Table 5: Values of $r_{\rm w}$ and $r_{\rm sp}$ for the sets of parameters that, for a given ${\delta }$ , give the best fit to the observed B/C ratio. The mean square value $\sqrt{\langle r^2 \rangle}$ of the distance to the sources is also shown.
Table 6: Fraction $f_{\rm s}$ (in %) of the Galactic sources contributing to a given fraction (90% and 99%) of the cosmic ray flux at the solar position, for protons and Fe nuclei, for the diffusion models studied before.
Table 7: Mean cosmic ray age $\langle t \rangle \sim \langle r^2 \rangle/2K$ in Myr for the models studied in this paper.
