Most importantly, the databases disseminated by PL on its web pages will serve as models of effective dissemination of scientific and engineering data. Work continues with various groups within NIST concerned with electronic information dissemination and with a professional society. We began providing information to the public in June 1994. The rate of use continues to increase rapidly. It ranges from staff and organization information to PL technical activities, publication lists, research facilities, news items, physical reference data, and bibliographic information about physical reference data.
New information is added regularly.
We develop programs to provide this information and innovations to overcome the limitations of current browsers. It provides information developed for scientists and technologists working in X-ray diffraction and related fields. It presents over the web, in graphical and tabular form, for each atom, the total attenuation coefficient, the photoelectric cross section, the sum of coherent and incoherent scattering, and self-consistent values of the atomic scattering factors f 1 and f 2 . Those using a web browser with a frames feature can have both tabular and graphical information delivered on the same screen. Others receive the same information sequentially.
