Title: The dominance of the $ν {(0 d_{5 / 2})}^{2}$ configuration in the N = 8 shell in 12 Be from the breakup reaction on a proton target at intermediate energy

Abstract

The momentum distribution of ¹¹Be fragments produced by the breakup of ¹²Be interacting with a proton target at 700.5 MeV/u energy has been measured at GSI Darmstadt. To obtain the structure information on the anomaly of the neutron shell, the momentum distribution of ¹¹Be fragments from the one-neutron knockout ¹²Be(p,pn) reaction, measured in inverse kinematics, has been analysed in the distorted wave impulse approximation (DWIA) based on a quasi-free scattering scenario. The DWIA analysis shows a surprisingly strong contribution of the neutron 0d_5/2 orbital in ¹²Be to the transverse momentum distribution of the ¹¹Be fragments. The single-neutron 0d_5/2 spectroscopic factor deduced from the present knock-out data is 1.39(10), which is significantly larger than that deduced recently from data of ¹²Be breakup on a carbon target. This result provides a strong experimental evidence for the dominance of the neutron configuration in the ground state of ¹²Be.

The sensitivity of the rare decays η^(') → π⁰γγ and η' → ηγγ to signatures of a leptophobic B boson in the MeV–GeV mass range is analyzed in this work. By adding an explicit B-boson resonance exchange, η → Bγ → π⁰γγ, to the Standard Model contributions from vector and scalar meson exchanges, and employing experimental data for the associated branching ratios, it allows us to improve the current constraints on the B-boson mass mB and coupling to Standard Model particles α_B. From these constraints and the analysis of the available experimental γγ invariant mass distribution, we show that amore »« less
