Confirmation of the isomeric state in 26P

Abstract

We report the independent experimental confirmation of an isomeric state in the proton drip-line nucleus 26P. The γ-ray energy and half-life determined are 164.4±0.3(sys)±0.2(stat) keV and 104±14 ns, respectively, which are in agreement with the previously reported values. These values are used to set a semiempirical limit on the proton separation energy of 26P, with the conclusion that it can be bound or unbound.
