| backscattered electron | <microscopy> Produced by an incident electron colliding with the nucleus of an atom in the specimen. The incident electron is then scattered backward about 180 degrees with no appreciable loss of energy, an elastic collision. (05 Aug 1998) |
| backscattered electron imaging | <microscopy> The production of backscattered electrons from a sample varies directly with the specimen's average atomic number, higher atomic number elements produce more backscattered electrons than lower atomic number ones. Detection of Backscattered Electrons is achieved by using a donut shaped solid state saemiconductor device mounted on the bottom of the objective lens. When Backscattered Electrons strike the detector electron-hole pairs are created which are then counted. This quantity is translated into a pixel intensity and displayed on the CRT, forming the image. By splitting the detector into halves (or quadrants) differences in the signal level on the individual detector segments provide surface topography information. (05 Aug 1998) |
| backscattering | <radiobiology> Deflection of incident particle / radiation through an angle greater than 90 degrees relative to the original direction of motion/propagation. (09 Oct 1997) |
| backside | The hinder part, posteriors, or rump of a person or animal. Backside (one word) was formerly used of the rear part or side of any thing or place, but in such senses is now two words. Origin: Back, a. + side. Source: Websters Dictionary (01 Mar 1998) |
