Descriptor microscopía nuclear
Scope note: Método de obtención simultánea de imágenes y mediciones de elementos de tamaño submicrométrico. La microscopía nuclear emplea haces de iones focalizados de alta energía, de PROTONES y PARTÍCULAS ALFA (microsonda nuclear) para interaccionar con la muestra. Las radiaciones emitidas se analizan simultáneamente con un conjunto de técnicas: ESPECTROMETRÍA POR EMISIÓN DE RAYOS X INDUCIDOS POR PARTÍCULAS para la identificación de elementos menores y traza, espectroscopia de retrodispersión de Rutherford para valorar el espesor de la muestra y elementos básicos como carbono, hidrógeno, oxígeno y nitrógeno y microscopía iónica de transmisión de barrido para valorar la estructura y densidad de la muestra.

Scope note: A method of simultaneously imaging and measuring elements at the submicron level. Nuclear microscopy uses a focused high-energy ion beam of PROTONS and ALPHA PARTICLES (a nuclear microprobe) to interact with the sample. The resulting emitted radiations are analyzed by a group of techniques simultaneously: PARTICLE INDUCED X RAY EMISSION SPECTROMETRY for minor and trace element identification; Rutherford Backscattering Spectroscopy to assess sample thickness and bulk elements such as carbon, hydrogen, oxygen, and nitrogen; and Scanning Transmission Ion Microscopy to assess sample structure and density.
