“…This limit, however, is typically not sufficient to obtain converged results for nuclei beyond A = 100 as discussed in Refs. [18,[20][21][22]41], and which we also demonstrate below. Towards heavier systems, the contributions of the residual 3N interactions is expected to be comparable to the truncation error of the many-body method [42].…”

We propose a novel storage scheme for three-nucleon (3N) interaction matrix elements relevant for the normal-ordered two-body approximation used extensively in ab initio calculations of atomic nuclei. This scheme reduces the required memory by approximately two orders of magnitude, which allows the generation of 3N interaction matrix elements with the standard truncation of E3 max = 28, well beyond the previous limit of 18. We demonstrate that this is sufficient to obtain ground-state energies in 132 Sn converged to within a few MeV with respect to the E3 max truncation.In addition, we study the asymptotic convergence behavior and perform extrapolations to the untruncated limit. Finally, we investigate the impact of truncations made when evolving free-space 3N interactions with the similarity renormalization group. We find that the contribution of blocks with angular momentum J rel > 9/2 is dominated by a basis-truncation artifact which vanishes in the large-space limit, so these computationally expensive components can be neglected. For the two sets of nuclear interactions employed in this work, the resulting binding energy of 132 Sn agrees with the experimental value within theoretical uncertainties. This work enables converged ab initio calculations of heavy nuclei.

“…The observation of a 3563(1)-keV transition in this work implies that this neutron-unbound (11/2 − ) state is also populated via the β1n decay of 134 In. A certain analogy can be noted to the population pattern observed in the βn decay of 132 In, which proceeds primarily through the high-spin (11/2 − ) isomer in 131 Sn [40,76]. In the β decay of 134 In, states with configurations involving neutron hole in the ν1h 11/2 orbital are populated in each observed β-decay branch.…”

The β decay of the neutron-rich 134 In and 135 In was investigated experimentally in order to provide new insights into the nuclear structure of the tin isotopes with magic proton number Z = 50 above the N = 82 shell. The β-delayed γ-ray spectroscopy measurement was performed at the ISOLDE facility at CERN, where indium isotopes were selectively laser-ionized and on-line mass separated. Three β-decay branches of 134 In were established, two of which were observed for the first time. Population of neutron-unbound states decaying via γ rays was identified in the two daughter nuclei of 134 In, 134 Sn and 133 Sn, at excitation energies exceeding the neutron separation energy by 1 MeV. The β-delayed one-and two-neutron emission branching ratios of 134 In were determined and compared with theoretical calculations. The β-delayed one-neutron decay was observed to be dominant β-decay branch of 134 In even though the Gamow-Teller resonance is located

“…Neutron-rich indium isotopes around the doubly magic 132 Sn nucleus are a center of attention and they are extensively studied via a plethora of experimental methods, such as mass measurements [1][2][3][4], laser spectroscopy [5,6], decay spectroscopy [7][8][9][10][11][12][13][14][15][16][17][18], and transfer reactions [19]. It is because nuclei around the doubly magic core are relatively simple systems and they constitute a perfect testing ground for various theoretical approaches [20][21][22][23][24][25].…”
