A study of the pulsed optogalvanic effect in a Sr/Ne hollow cathode tube for Penning ionization spectroscopy in this system is described. In the case of strontium this ionization is a multichannel process due to the quasi-resonance between the four excited 3s states of neon with the high density of Rydberg states close to a Sr+ ionization continuum. A detailed investigation of the signal as a function of tube current and its spatial dependence as well as a comparison with Ca/Ne Penning rate is also reported.
