By exploiting the Doppler Shift Attenuation Method, the lifetime of the 2+ 2 and 3+ 1 states were firmly established. From the γ-ray branching and E2/M1 mixing ratios for transitions deexciting the 2+ 2 and 3+ 1 states, the B(E2) and B(M1) were determined. Various chiral effective field theory Hamiltonians, describing the nuclear properties beyond ground states, along with a standard USDB interaction, were compared with the experimentally obtained data. Such a comparison for a large set of γ-ray transition probabilities with the valence space in medium 2 similarity renormalization group ab-initio calculations was performed for the first time in a nucleus far from stability. It was shown that the ab-initio approaches using chiral EFT forces are challenged by detailed high-precision spectroscopic properties of nuclei. The reduced transition probabilities were found to be a very constraining test of the performance of the ab-initio models
