摘要:

The first systematic study of archaeological objects with muonic X‐rays is reported. In this analysis every element is recognized. The elemental composition of Celtic glasses from Bavaria and Roman coins has been determined. By selecting the primary muon energies appropriately my part of the specimen, including interior parts, can be non‐destructively in estigated. Additionally surface layers may be analysed. Typical accuracies of quantitative analyses are a few per cent of elemental abunda

摘要:

A simple optical method is described that will enhance the color contrast between the outer birefringent hydration rind and the inner unhydrated core on obsidian thin sections used for hydration dating. The technique utilizes a gypsum nccessory plate. The gypsum plate rotates all incoming light by 550nm causing the black isotropic core of the nhsidian to become transparent first‐order pink and interacting with the transmitted light from the birefringent rind, by either addition or subtraction. to produce a second‐order blue or a first‐order yellow
