48X-ray absorption fine structure — (XAFS) is a specific structure observed in X ray absorption spectroscopy (XAS). By analyzing the XAFS, information can be acquired on the local structure and on the unoccupied electronic states.The X ray absorption spectra show a steep rise at… …
49Katko v. Briney — 183 N.W.2d 657 (Iowa 1971), was a famous tort case decided by the Supreme Court of Iowa, in which a homeowner (Edward Briney) was held liable for battery for injuries caused to a trespasser (Marvin Katko) who set off a spring gun set as a mantra …
50Inverse photoemission spectroscopy — (IPES) is a surface science technique used to study the unoccupied electronic structure of surfaces, thin films and adsorbates. A well collimated beam of electrons of a well defined energy (< 20 eV) is directed at the sample. These electrons… …
