摘要：
The Similarity Renormalization Group reduces the off-shellness by driving the evolved interaction towards a diagonal band. We analyze the infrared limit and the corresponding on-shell interactions and its consequences for light nuclei. Using a harmonic oscillator shell model we obtain a Tjon line Bα = 4Bt − 3Bd which can be understood from a combinatorics counting of nucleon pairs and triplets in the triton and α-particle and compares favorably with realistic calculations.
