Theoretical and Experimental Understanding of the Anomalous Odd-to-Even Isotope Ratios of Tin in a 1 + 1 Single-Colour Resonance Ionization Mass Spectrometry: Revisited

Table 7

A table of the experimentally determined abundances and responses of the odd and even isotopes. Experimentally determined anomaly (𝛽) as a function of laser frequency detuning for collinear-RIMS.
