Shell structure of Ti and Cr nuclei from measurements ofgfactors and lifetimes

$g$ factors and lifetimes have been measured for the first $2^{+}$ and $4^{+}$ states of ${}^{46,48}\mathrm{Ti}$ and ${}^{50,52}\mathrm{Cr}$ employing the combined technique of projectile Coulomb excitation and transient magnetic fields. The same target was used in all measurements. The individual isotopes were provided by the ion source of the accelerator. These conditions guarantee high reliability and precision as demonstrated in earlier experiments. While the global behavior of the data is well explained by full $\mathrm{fp}$ shell model calculations, distinct deviations from theoretical predictions for ${}^{46,48}\mathrm{Ti}$ might be attributed to excitations of the ${}^{40}\mathrm{Ca}$ core.
