The improved limits obtained in the modified experiment of Pauli exclusion principle using accelerator mass spectrometry is presented. Rather than using conventional mass spectrometry techniques, the experiment utilizes PRIME Lab-the Purdue Accelerator Mass Spectrometer, which has far greater sensitivity. Samples were chosen where the probability of Be′ retention is highest. The assumption behind the use of the gas sample is that a geological region capable of trapping He might also trap Be′, which may arise from outgassing of the Earth's crust or through direct cosmic ray production.
