Low-lying states in ¹²Be using one-neutron transfer reaction

NUCLEAR REACTIONS ^1,2H(¹¹Be, ¹¹Be), (¹¹Be, p), E=26.9 MeV/nucleon; measured recoils, Ep, Ip, p(θ), Eγ and Iγ from decay of recoils, (recoil)p-coin, differential σ(θ) for low-lying 0+, 2+ and 1- states in ¹²Be, half-life of excited 0+ isomer by decay-tagging method using (CH₂)_n and (CD₂)_n targets, annular silicon detectors (ADSSD) for protons, detector telescopes for charged particle detection, and scintillation detectors for γ detection, and isomer-tagging method at RCNP-Osaka. DWBA analysis of σ(θ) data. ¹²Be; deduced levels, J, π, spectroscopic factors, single-particle components in the g.s. and excited 0+ state. Comparison with shell-model calculations, and with previous experimental results. ^11,12Be; calculated B(E2), B(E1), S(n) and S(2n) from shell-model, and compared with experimental data in literature.
