Proton total reaction cross sections for 700 MeV protons on /sup 40,44,48/Ca have been measured by detecting inelastically scattered particles at angles greater than 10/sup 0/ (lab). The measurements were performed with overall uncertainties of +- 6.2% and relative uncertainties of +- 2.5%. These measurements yield the values of sigma/sub R/(/sup 40/Ca) = 614 mb, sigma/sub R/(/sup 44/Ca) = 643 mb, and sigma/sub R/(/sup 48/Ca) = 736 mb. Matter radii differences ..delta.. (44-40) = (0.05 +- 0.09)fm and ..delta.. (48-40) = (0.36 +- 0.09)fm were extracted based on a theoretical calculation which takes advantage of the geometrical nature of the cross section. The results are compared to other available measurements of total reaction cross sections on medium-weight nuclei at medium energies and to other determinations of the matter radii differences for the calcium isotopes.
