Determination of lithium ion–rare gas potentials from total cross section measurements

Total cross sections have been measured for Li+ ions scattered by He, Ne, Ar, Kr, and Xe in the range EϑR = 5–1000 eV deg. Here E is the laboratory energy of the Li+ beam, and ϑR is the resolution angle of the apparatus. The cross sections have been inverted to obtain accurate estimates of the potential V(R) over a wide range of R including the attractive well region. The results are compared with other theoretical and experimental work on these systems.
