Using the photon-ion merged-beam technique, we have measured the absolute p
hotoionization cross sections for Xe2+ and Xe3+ formation from Xe+ at selec
ted energies between 80 and 140 eV, and utilized the absolute data to norma
lize our previously reported relative cross sections. The structure and ene
rgy dependence of the cross sections for Xe+ deviate from those of neutral
Xe; however, the maximum total cross section for Xe+ is, within the experim
ental error, the same as for Xe.
