Current status and desired precision of the isotopic production cross sections relevant to astrophysics of cosmic rays. II. Fluorine to silicon and updated results for Li, Be, and B

High-precision cosmic-ray (CR) data from ongoing and recent past experiments (Voyager, ACE-CRIS, PAMELA, ATIC, CREAM, NUCLEON, AMS-02, CALET, DAMPE) are being released in the tens of the MeV/n to multi-TeV/n energy range. Astrophysical and dark matter interpretations of these data are limited by the precision of nuclear production cross sections. In Paper I [Phys. Rev. C 98, 034611 (2018)], we set up a procedure to rank nuclear reactions whose desired measurements will enable us to fully exploit currently available data on CR Li to N ($Z=3$--7) species. Here we extend these rankings to O up to Si nuclei ($Z=8$--14), also updating our results on the LiBeB species. We also highlight how comprehensive new high-precision nuclear data that could, e.g., be obtained at the Super Proton Synchrotron at CERN would be a game changer for the determination of key astrophysical quantities (diffusion coefficient, halo size of the Galaxy) and indirect searches for dark matter signatures.
