由于缺乏对介子停止位置的精确了解，从介子-自旋弛豫实验中获得的信息可能是有限的。在这里，我们证明了在含氟分子材料中，处于已知停止态的自旋极化的介子局域化的可能性。由介子自旋和周围的核自旋的纠缠性质产生的介子-自旋进动对停止点的性质很敏感。我们使用这一性质来识别分子磁体中出现的三类位置，并描述介子扭曲其周围环境的程度。
The information accessible from a muon-spin relaxation experiment can be limited due to a lack of knowledge of the precise muon stopping site. We demonstrate here the possibility of localizing a spin polarized muon in a known stopping state in a molecular material containing fluorine. The muon-spin precession that results from the entangled nature of the muon spin and surrounding nuclear spins is sensitive to the nature of the stopping site. We use this property to identify three classes of sites that occur in molecular magnets and describe the extent to which the muon distorts its surroundings.
