The neutron is suitable for cultural heritage research since it has high penetration power and can investigate the interior of metals noninvasively. The Jap发誓放弃 发表于 2025-3-24 04:09:30

Depth-Dependent Bulk Elemental Analysis Using Negative Muonsnt coins to statues to meteorites to biomaterials. These studies use negative muons, which with a controllable momentum have a well-defined implantation depth (from microns to cm). This technique has many similarities to X-ray fluorescence, except that the negative muon has a mass ~200 times greaterpainkillers 发表于 2025-3-24 23:18:27
