2015, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and AtomsCitation Excerpt :If the electron affinity of the unwanted isobar is lower than the electron affinity of the ion of interest, the photon wavelength can be chosen such that only the interfering species is neutralized while the ion of interest remains negatively charged (Fig. 1). Proof of principle of this so-called optical filtering was shown in demonstration experiments for the cases 36Cl−36S [8] and 59Ni−59Co [9]. However, the reported isobar suppression was far from being useful for AMS measurements.

2008, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and AtomsCitation Excerpt :Tuning the laser to a frequency lower then the EA of the radioisotope but higher than the one of the stable isobar, only the latter will be photodetached and hence neutralized. A proof of principle of the selective photodetachement was shown in demonstration experiments for the cases 36Cl–36S and 59Ni–59Co [3,4]. However, the reported overall degree of isobar suppression was far from being practically useful for actual AMS measurements without further improvements.
