Abstract
We report the results of a new experimental search for the Pauli-forbidden state of Be, denoted by . Using the Accelerator Mass Spectrometer facility at Purdue University, we set limits on the abundance of in metallic Be, Be ore, natural gas, and air. Our results improve on those obtained in a previous search for by a factor of approximately 300.
