Unstable nuclei induced nuclear reactions

The excited states of unstable ²⁰O were investigated via γ-ray spectroscopy following the ¹⁹O(d, p) ²⁰O reaction at 8 AMeV. By exploiting the Doppler shift attenuation method, the lifetimes 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 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 effective field theory 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.
