Abstract

If the Pauli exclusion principle were violated, the electronic structure of Be could be 1s4 (denoted by Be(′)) rather than 1s22s2. This paper describes the results of an experimental search for Be(′), carried out at PRIME Lab, the Purdue Rare Isotope Measurement Laboratory. In the process of setting stringent constraints on Be(′) using samples of metallic Be, Be ore, natural gas, and air, we made several modifications to the PRIME Lab facility. These included a new Be-free source and the construction of a gas introduction system which coupled to the existing ion source. The modifications permitted us to reach limits which are a factor of nearly 300 better than those obtained in previous experiments.
