Abstract Two short-lived isomeric states in118Sb have been investigated by the118Sn(p, n),118Sn(d, 2n) and115In(α, n) reactions. The TDPAD method on solid and liquid metallic targets was used to measure the electromagnetic moments of these states. The results of the experiments are: $$\begin{gathered} T_{1/2} = 13.4{\text{ }}(3){\text{ }}ns I^\pi = 3^ - {\text{ }}g = - 1.254(31){\text{ }}|Q| = 0.25{\text{ }}(5){\text{ }}b, \hfill \\ T_{1/2} = 22.8{\text{ }}(4){\text{ }}ns I^\pi = 7^ + {\text{ }}g = + 0.680(18){\text{ }}|Q| 〉 1.4{\text{ }}b. \hfill \\ \end{gathered}$$ Pure $$[\pi 2d_{5/2} \otimes v1h_{1{\text{ }}1/2} ]_{3 - }$$ and $$[\pi 1g_{9/2}^{ - 1} \otimes v2d_{5/2}^{ - 1} ]_{7 + }$$ configurations have been established for the two isomeric states. An experimental evidence concerning the participation of the 1g 9 2/−1 proton shell-model intruder excitation into the positive parity low-lying level structure of the odd-odd118Sb nucleus was obtained.
