A new free-access database of constant-wavelength powder
diffraction patterns, PowBase, is searchable online at :

The current content is already 79 patterns (conventional
X-ray, synchrotron, neutron) presenting typical cases for
high or low resolution, line broadening effects, standard
materials, ab initio structure determination, etc. This is
almost 3% of the future ICDD PDF-3 database after 4
days of existence. Enlarging the base depends on you.
Send your data, published or not, inorganic as well as
organic !
