The level schemes and transition rates {\em B}({\em E}2;↑) of
eve-even 48−56Ti isotopes were studied by performing large-scale shell
model calculations with FPD6 and GXPF1 effective interactions. Excellent
agreement were obtained by comparing the first 2+ level for all isotopes
with the recently available experimental data, but studying the transition
strengths {\em B}({\em E}2; 0g.s.+​→21+​) for all Ti isotopes using
constant proton-neutron effective charges prove the limitations of the present
large-scale calculations to reproduce the experiment in detail.Comment: 4 pages, 4 figure
