Proton total reaction cross sections have been measured for the doubly magic nuclei $sup 16$O, $sup 40$Ca, and $sup 208$Pb in the energy range 20--50 MeV. For the p+$sup 16$O system, total reaction cross sections were measured in 400 keV steps over practically the entire energy range. The p+$sup 40$Ca and p+$sup 208$Pb total reaction cross sections were measured at six and nine different energies, respectively. The experimental total reaction cross sections are compared with results based on optical model analyses in which preliminary data from the present experiment were included. An evaluation of the imaginary potential parameters is reported. Using the proton total reaction cross section information for $sup 16$O, $sup 40$Ca, and $sup 208$Pb available in the literature, general characteristics of these cross sections in the energy range 10--1000 MeV are shown. A comparison has been made between the measured total reaction cross sections and those predicted by global optical model parameter sets.
