β decay of the neutron-rich nuclides 55,56Ti has been used to populate low-energy levels of 55,56V, respectively. A half-life of 1.3±0.1 s was deduced for 55Ti, significantly longer than that determined from previous measurements. The β decay of 56Ti is characterized by a short half-life of 200±5 ms, with nearly all of the decay directly populating the 1+ ground state of 56V. The role of the spin-flip process νf5/2→πf7/2 in defining the β-decay properties of nuclei near N=32, including 55,56Ti, is discussed.
