Abstract Neutron resonance capture analysis (NRCA) is a method that utilizes the resonance structures in neutron-induced reactions to determine the elemental composition of materials. It is used for the non-destructive analysis of cultural heritage objects, archaeological artifacts, and reference materials. The back streaming white neutron facility (Back-n) of the China Spallation Neutron Source (CSNS) provides neutron energy ranging from eV to MeV, offering favorable beam conditions for the development of neutron resonance capture imaging (NRCI). Compton imaging is applied to achieve NRCI in this work. A series of dedicated measurements with calibrated sources and with Back-n neutron beam incident on a 197Au sample have been carried out. The results indicate that this detector can achieve NRCI at Back-n. This work provides a foundation for nuclide identification using NRCI at the Back-n facility.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
