Neutron Resonance Analysis Methods for Archaeological and Cultural Heritage Applicationsussed. This can be done by detecting prompt γ-rays, which are emitted after a neutron capture reaction in the object being studied. This technique, known as neutron resonance capture analysis (NRCA), is sensitive to almost all stable nuclides and can be applied to determine the elemental and isotopi大笑 发表于 2025-3-25 17:43:01
Small-Angle Neutron Scattering for Cultural Heritage Studieseld of cultural heritage. It describes the theoretical background of the method and presents two SANS instruments of different types operating at the Budapest Neutron Centre. Two examples of early medieval pottery wares and geological obsidian samples are shown.松软无力 发表于 2025-3-25 21:42:35

Integration of Neutron-Based Elemental Analysis and Imaging to Characterize Complex Cultural Heritag to characterize homogeneous artifacts, such as stone tools, glassware, pottery, coins, bronze or iron items, gold and silver artifacts, as presented in Chap. 46. However, many heritage objects are composite. Here, instead of a bulk average, the local elemental composition should be determined, and慷慨援助 发表于 2025-3-26 07:09:01
Ancient Buddhist Metal Statues Using Neutron Tomographysecrated fillings, mostly organic materials and substances, done several hundred years ago, is reported..It is the advantage of neutrons to penetrate dense metal layers – as bronze or brass – and to provide a high contrast to lighter elements (H, C, O, etc.). These specific characteristics of neutroLeisureliness 发表于 2025-3-26 09:44:40
Neutron Activation Autoradiography for Investigation of paintingsasters. The NAR technique allows for visualization of different paint layers, based on the detection of different dominant radioisotopes produced by neutron irradiation, in contrast to the X-ray radiography which is sensitive to the distribution of heavy elements only. In many cases, the individualLignans 发表于 2025-3-26 13:21:50
ECHO: The ELETTRA Cultural Heritage Officeof cultural heritage (CH) science, offering a portfolio of non- or micro-destructive analytical techniques to a wide community of archaeologists, art historians, conservators, and restorers.
