Abstract
The Pauli Exclusion Principle (PEP) was tested with the NEMO-2 detector. Li mits at the 90% C.L. on the violation of PEP for p-shell nucleons in C-12 w ere obtained. Specifically transitions to the fully occupied 1s(1/2)-shell yielded a limit of 4.2 . 10(24) y for the process with emission of a gamma- quantum. Similarly limits of 3.1 . 10(24) y for beta(-) and 2.6 . 10(24) y for beta(+) Pauli-forbidden transitions of C-12 -->(12) (N) over tilde((12) (B) over tilde) are reported here.
