Limits on Pauli principle violation by nucleons

Abstract

We consider nuclei produced in core collapse supernovae and subjected to a high neutron flux. We show that an accelerator mass spectrometry experiment that searched for traces of anomalous iron isotopes could set limits on the order of $10^{-20}-10^{-25}$ on (or perhaps discover) Pauli principle violation by neutrons. A similar search for anomalous Co isotopes could set limits in the range $10^{-13}-10^{-18}$ on Pauli principle violation by protons. We show that existing data on Oxygen can be used to set a limit of about $10^{-17}$ in one proposed model of such violation.
