Gamma rays from {sup 52}Ti have been studied with Gammasphere and the Fragment Mass Analyzer using reactions induced by a {sup 48}Ca beam on a {sup 9}Be target. The data have been used in combination with information from deep-inelastic reactions of {sup 48}Ca beams on a thick {sup 238}U target at an energy about 25% above the Coulomb barrier. The {sup 52}Ti level scheme was expanded considerably, and the lifetimes of some of the identified states were determined for the first time. The excitation of two protons and two neutrons outside the {sup 48}Ca core provide new tests of effective interactions in the full pf-shell model space. The positive-parity states in {sup 52}Ti were compared to theoretical predictions obtained with the GXPF1A, FPD6, and KB3G effective interactions. The comparisons favor, to a degree, the results computed with the GXPF1A interaction.
