Query: Do neutrons publish? A neutron publication survey 2005-2015   Publication in scientific journals is the main product of scientific
research. The amount of papers published, their placement in high impact
journals, and their citations are used as a measure of the productivity of
individual scientists, institutes or fields of science. To give a profound
basis on the publication record and the quality of the publication efforts in
neutron scattering, a survey has been done following the approach to use
bibliographic databases. Questions to be addressed by this survey are: Is the
productivity of research with neutrons changing over the years? Which is the
geographic distribution in this field of research? Which ones are leading
facilities? Is the quality of publications changing? The main results found are
presented.
