Enhancement of accuracy of neutron atomic resolution holography

Neutron Holography 3-D Atomic Images

Simulation studies of atomic resolution X-ray holography

X-ray holography is a new method of structure determination based on measurement of interference of a known reference wave with an unknown object wave (containing information on atomic sites scattering the reference wave) so that phase information is preserved. Unlike X-ray diffraction, it does not demand for translational periodicity in the material. It is based on the idea similar to that of ...

Development of Holography Electron Microscope with Atomic Resolution

THE transmission electron microscope was invented in Germany in 1932. It works by directing a beam of electrons through a specimen and then using a lens to enlarge the image formed by their passage. In Japan, development and research into its applications began in 1939, and numerous companies around the world have competed to develop the instruments since Hitachi developed its own fi rst transm...

Atomic Resolution g-ray Holography Using the Mössbauer Effect

We have observed a strong (2%) angular modulation of the total backscattered conversion electron yield, measured as a function of the incidence angle of the 14.4 keV g rays from a 57Co Mössbauer source irradiating thin epitaxial 57Fe film grown on MgO(001). The measured 2D pattern is the first hologram of the local surrounding of the absorbing nuclei obtained due to nuclear resonant scattering ...

the effects of time planning and task complexity on accuracy of narrative task performance

هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...
