WebOne means by which a continuous spectrum can be produced is by thermal emission from a black body. This is particularly relevant in astronomy and is discussed in the next … WebCharacteristic X-rays are produced when an element is bombarded with high-energy particles, which can be photons, electrons or ions (such as protons). When the incident particle strikes a bound electron (the target electron) in an atom, the target electron is ejected from the inner shell of the atom. WebSpectrum [DiFMUP (pH 9.0)] DiFMUP (pH 9.0) is a fluorescent compound with an excitation peak at 358 nm and an emission peak at 450 nm, giving it a fairly large Stokes' Shift of 92nm. It can be excited using a 355 nm laser paired with a 450/50 nm bandpass filter, a configuration that can be found, for example, in the BD Special Order LSRFortessa ... can adhd have tics
