A systematic analysis is made on the total reaction cross sections for Ne, Mg, Si, and S isotopes. The high-energy nucleus-nucleus collision is described based on the Glauber model. Using the Skyrme-Hartree-Fock method in the three-dimensional grid-space representation, we determine the nuclear density distribution for a wide range of nuclei self-consistently without assuming any spatial symmetry. The calculated total reaction cross sections consistently agree with the recent cross section data on the Ne+C-12 collision at 240 AMeV, which makes it possible to discuss the radius and deformation of the isotopes. The total reaction cross sections for Mg+C-12, Si+C-12, and S+C-12 cases are predicted for future measurements. We also find that the high-energy cross section data for O, Ne, and Mg isotopes on a C-12 target at around 1000 AMeV can not be reproduced consistently with the corresponding data at 240 AMeV.
