Quenching of the π₀p_3/2-π₀p_1/2 Spin-Orbit Splitting in ²⁰O and the Effect of the Tensor Force

NUCLEAR REACTIONS ²H(²⁰O, ³He), E=35 MeV/nucleon; measured reaction products. ²⁰O, ¹⁹N; deduced the excitation energy spectrum of ¹⁹N, σ(θ), spectroscopic factors, the proton spin-orbit splitting, the effects of the tensor force predicted by state-of-the-art shell model interaction SFO-tls. The ACTAR TPC setup at GANIL.
