Nineteen levels up to 5.1 MeV in /sup 52/Ti and 52 levels up to 4.7 MeV in /sup 53/V have been identified using the /sup 50/Ti(t,p) and /sup 51/V(t,p) reactions. Measured angular distributions were compared with results of distorted-wave Born-approximation calculations. In /sup 52/Ti, the experimental angular distributions agree with distorted-wave Born-approximation shapes for four states whose J/sup ..pi../ values were previously known. For six levels we make clear L (and hence J/sup ..pi../) assignments, and we present tentative assignments for six additional levels. In /sup 53/V, no discrepancies were found between spin assignments suggested in earlier studies and the spin limitations imposed by the L values extracted from the (t,p) angular distributions. The present results along with the experimental results from an earlier /sup 55/Mn(t,p)/sup 57/Mn study were used to test mixed-configuration shell-model calculations for the three residual nuclei. The agreement between the experimental and predicted level schemes is good up to 1.5 MeV, but above this energy a number of levels are present which are not predicted by the calculation. The shell-model wave functions were also used to calculate spectroscopic amplitudes for two-nucleon transfer reactions. In all three residual nuclei, fair agreement is found between the experimental strengths and the strengths predicted by the calculations.
