64Mössbauer spectroscopy — A Mössbauer absorption spectrum of 57Fe Mössbauer spectroscopy is a spectroscopic technique based on the Mössbauer effect. This effect, discovered by Rudolf Mössbauer in 1957, consists in the recoil free, resonant absorption and emission of gamma …
65Single molecule electronics — is a branch of molecular electronics that uses single molecules as electronic components. Because single molecules constitute the smallest stable structures imaginable this miniaturization is the ultimate goal for shrinking electrical circuits.… …
66Transition metal — The term transition metal (sometimes also called a transition element) has two possible meanings: The IUPAC definition[1] states that a transition metal is an element whose atom has an incomplete d sub shell, or which can give rise to cations… …
67Rydberg formula — The Rydberg formula is used in atomic physics to describe the wavelengths of spectral lines of many chemical elements. The formula was invented by the Swedish physicist Johannes Rydberg and presented on November 5, 1888.HistoryIn the 1880s,… …
68Radiation chemistry — is a subdivision of nuclear chemistry which is the study of the chemical effects of radiation on matter; this is very different from radiochemistry as no radioactivity needs to be present in the material which is being chemically changed by the… …
69History of electromagnetism — The history of electromagnetism, that is the human understanding and recorded use of electromagnetic forces, dates back over two thousand years ago, see Timeline of electromagnetism. The ancients must have been acquainted with the effects of… …
70Auger effect — /oh zhay /, Physics. a nonradiative process in which an atom in an excited state undergoes a transition to a lower state by the emission of a bound electron (Auger electron) rather than by the emission of an x ray. Also called autoionization.… …
