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 semi-empirical limit on the proton separation energy of 26P, with the conclusion that it can be bound or unbound.
