Gamma rays from neutron-rich nuclei in the vicinity of Z=20, N=28 have been studied at Gammasphere using deep-inelastic reactions induced by a 330-MeV {sup 48}Ca beam on a thick {sup 238}U target. The yrast {gamma}-ray cascade of {sup 56}Ti was identified for the first time and the location in energy of the 2{sup +}, 4{sup +}, and 6{sup +} states was determined. The low-spin {sup 56}Ti yrast structure does not support the presence of a subshell closure at N=34 as suggested on the basis of other data on nuclei in the region as well as shell model calculations with a recently proposed interaction.
