First measurement of the B(E2; 3/2^- → 1/2^-) transition strength in ⁷Be: Testing ab initio predictions for A = 7 nuclei

NUCLEAR REACTIONS ¹⁹⁷Au(⁷Be, ⁷Be'), E=31.3 MeV, [secondary ⁷Be beam from ²H(⁶Li, n), E=34.0 MeV primary reaction]; measured reaction products, particle spectra, Eγ, Iγ, (particle)γ-coin using silicon detector for charged particle detection and HPGe detectors for γ detection at the University of Notre Dame FN Tandem Van de Graaff accelerator facility. ⁷Be; deduced levels, J, π, Coulomb excitation cross section, B(E2) for 3/2- to 1/2- (g.s. to the first excited state) transition. Comparison with ab initio no-core shell model (NCSM) calculations.
