The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Our results demonstrate that dissociative double ionization of ozone produces electronically excited cationic atomic oxygen fragments in addition to the ground-state dissociation pathway, revealing a richer fragmentation dynamics than hitherto recognized.

C2weakest assumption

The assignment of experimental spectral features to specific dissociation channels depends on the accuracy of post-Hartree-Fock multi-configurational-interaction calculations for the dication potential energy surfaces and energetics.

C3one line summary

First single-photon double ionization spectrum of ozone shows dissociative pathways yielding electronically excited cationic oxygen fragments beyond the ground-state channel.
