Surveying Hebel-Slichter peaks in conventional-ish superconductors

The presence of a Hebel-Slichter peak in NMR or µSR measurements just below the critical temperature of superconductors is taken to be strong evidence for conventional behaviour...在超导体临界温度以下的核磁共振（Nuclear Magnetic Resonance, NMR）或μ子自旋弛豫（Muon Spin Relaxation, µSR）测量中，若观测到赫贝尔-斯利希特峰（Hebel-Slichter peak），则该现象被视为证明常规超导行为存在的强有力证据……
