The level structure of V was studied for the first time by the inelastic proton scattering and the proton knock-out reaction. The comparison of the newly observed -ray transitions at 696(8) keV and 889(16) keV with our shell-model calculations using the Lenzi-Nowacki-Poves-Sieja interaction established two excited states proposed to be the first 11/2 and 9/2 levels. The (,) excitation cross sections were analyzed by the coupled channel formalism assuming pure quadrupole as well as quadrupole+hexadecapole deformations. This resulted in large deformation parameters placing V in the island of inversion located below Ni.
