Proton-stopping cross sections and mean excitation energies for gaseous Cl/sub 2/ and Br/sub 2/
Journal Article

· Phys. Rev. A; (United States)
First measurements of proton stopping powers in gaseous Cl/sub 2/ and Br/sub 2/ are reported for the energy range between 50 and 750 keV with statistical and systematical errors of about 1% each. In the stopping-power maximum the experimental values are higher than those predicted by the Andersen-Ziegler tables; moreover, lower peak energies are found. Experimental shell corrections were deduced from the proton stopping cross sections and adjusted to the theoretical predictions of Bonderup, whereby higher-order Z/sub 1/ correction terms were included. Within this procedure semiempirical values for the mean ionization potentials of 174 eV for Cl/sub 2/ and 363 eV for Br/sub 2/ were obtained.
