Abstract
We have investigated isotope selective resonance ionization (mass) spe ctrometry of strontium (Sr) for applications in trace-element analysis and isotope enrichment, making use of pulsed dye lasers of broad band width and continuous-wave semiconductor diode lasers of narrow bandwid th, In this first part, theoretical calculations are carried out to ad dress the problems of isotope selectivity, saturation and line broaden ing effects, and maximum (quantifiable) ionization. The modelling appr oach is based on a density matrix formalism incorporating both quantum mechanical and experimental parameters.
