# Extended Data Table 4 Various measured quantities that are used towards calculating the scattering probability into each product state-pair

1. These include the number of cycles over which ion counts are accumulated Cexp, the number of simultaneous counts nsim, the background level nbkgd, and the background fluctuation $${\rm{\delta }}{n}_{{\rm{b}}{\rm{k}}{\rm{g}}{\rm{d}}}$$. The values for nsim, nbkgd, and $${\rm{\delta }}{n}_{{\rm{b}}{\rm{k}}{\rm{g}}{\rm{d}}}$$ are obtained after the momentum-based screening is applied. The coincidence counts for each state-pair are calculated as ncoin = nsim – nbkgd. Also included are the (base 10) logarithm of the state-specific P-values used towards hypothesis testing. †Energetically forbidden state-pairs.
