SUMMARY
The discussion centers on the concept of neutronium potentially existing in a metastable nuclear isomer state, which could theoretically extend its half-life. While excited states of hadrons typically have shorter half-lives than ground states, examples like sodium-22m and 180mTa illustrate that certain isomers can exhibit longer half-lives than expected. The conversation highlights that single hadrons do not demonstrate metastability, as they decay rapidly via strong or electromagnetic interactions, while weak interactions result in slightly longer lifetimes. The Pauli effect and bound-state beta decay are also discussed as significant phenomena affecting half-lives in nuclear physics.
