| Neutron scattering from materials allows scientists to (1)_________ the structure and (2)____________ of materials down to atomic (3) _______ scales. Materials can be studies that are of interest to scientists in many fields including materials science and engineering, physics, chemistry, earth science and biology. Because neutrons are (4) _________ they can penetrate deeply into materials and it is possible to obtain the bulk properties of large samples, or to scan at (5) ________ for the residual stress in engineering components to ensure they will perform safely in operation. It is also possible by low-angle (6) __________ to explore the properties of surfaces, buried interfaces and (7) ________ layered structures. The structure of membranes and materials of biological (8) ___________ can also be determined. The magnetic moment of the neutron allows (9)______ of magnetic properties and highly correlated systems. Since the 1950s many hundreds of neutron scattering experiments have been carried out at the NRU reactor at Chalk River, solving (10) _________ problems for industry sometimes with substantial economic impact and pushing back the frontiers of human (11) ________ of the world around us. Those experiments have contributed to the (12) _________ of many hundreds of highly qualified people across the spectrum of science. The NRC Canadian Neutron Beam Centre enjoys a strong international reputation, and connects Canadian scientists to international (13) __________ with over a 100 institutions in more than 20 countries during a typical five-year period. | EXPLORATION DYNAMIC LONG CHARGE DEEP REFLECT synthesis SIGNIFICANT STUDY PRACTICE UNDERSTAND EDUCATE collaborate |
