Confirmation of the isomeric state in 26P

Abstract

We report the independent experimental confirmation of an isomeric state in the proton drip-line nucleus ${}^{26}$P. The ${\hat{I}}^3$-ray energy and half-life determined are 164.4 $\pm$ 0.3 (sys) $\pm$ 0.2 (stat) keV and 104 $\pm$ 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 ${}^{26}$P, with the conclusion that it can be bound or unbound.
