5/2+[402] 10.8 ns isomeric level at 482 keV in 181Ta was Coulomb-excited by 225 MeV 58Ni, starting from 7/2+[404] ground state. Particle--\gamma and particle--\gamma --\gamma events were collected. Excitation through newly observed gamma-vibrational K\pi =3/2+ band turned out to be 50 times more efficient than direct excitation.
