## Abstract

The Pauli exclusion principle was tested by searching with accelerator mass spectrometry for non-Paulian atoms with three electrons in the K-shell and for non-Paulian nuclei with three protons or three neutrons in the nuclear 1 s_{1/2} shell. For non-Paulian atoms of {Mathematical expression} and {Mathematical expression} the following limits have been obtained: {Mathematical expression} and {Mathematical expression}. For non-Paulian nuclei of {Mathematical expression} and {Mathematical expression} with three protons or three neutrons, respectively, in the nuclear 1 s_{1/2} shell the following limits have been measured: {Mathematical expression} for a range of proton separation energies of {Mathematical expression} between 0 and 50 MeV and {Mathematical expression} for neutron separation energies between 0 and 32 MeV. The result for^{5}Li is used to deduce a limit for the probability β^{2}/2 of finding two colliding protons in the symmetric state with respect to exchange to be β^{2}/2<0.5.10^{-32}.
