Shell structure of Ti and Cr nuclei from measurements of g factors and lifetimes

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