Beam energy dependence of charged pion ratio in ${}^{28}$Si + In reactions

M. Sako, T. Murakami, Y. Nakai +10

The double differential cross sections for ${}^{nat}$In(${}^{28}$Si, ${\pi }^{\pm }$) reactions are measured at 400, 600, and 800 MeV/nucleon. Both ${\pi }^{+}$ and ${\pi }^{-}$ are found to be emitted is…
