    "abstract": "While the no-core shell model is a state-of-the-art microscopic approach to\nlow-energy nuclear structure, its intense computational requirements lead us to\nconsider time-honored approximations such as the Hartree-Fock (HF)\napproximation and the random phase approximation (RPA). We review RPA and point\nout some common misunderstandings, then apply HF+RPA to the no-core shell\nmodel. Here the main issue is appropriate treatment of contamination by\nspurious center-of-mass motion.",
