We have studied the production of long-lived, highly-excited, neutral hydrogen atom fragments following oxygen 1s inner-shell excitation/ionization of gas-phase water molecules using synchrotron radiation. Striking differences to fragment ion and low-$$n$$ neutral H yields are observed close to threshold. To investigate the decay pathways involved the neutral fragments were also detected in coincidence with H$$^+$$, O$$^{2+}$$, O$$^+$$, and OH$$^+$$ fragments.
