Poly(methyl methacrylate) and poly(vynil chloride) samples have been irradiated by a pulsed electron beam of 1.2 keV and 0.18 µs FWHM. The results show that H+ is the main ionic species to desorb after electron bombardment. In addition, other ionic fragments were also observed and assigned. These results show the potentiality of this technique in the study of ESD of polymers.por--BrasilQuímica Nova-Electron stimulated desorptionTime-of-flight spectrometerPolymersIrradiação de polímeros com feixe de elétrons: caracterização de íons positivos através da técnica de tempo-de-vôoIrradiation of polymers using electron beams: characterization of positive ions through the time-of-flight techniqueinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleRocco, Maria Luiza MirandaPontes, Frederico CelestinoFaraudo, Gustavo SebastianSouza, Gerardo Gerson Bezerra deWeibel, Daniel Eduardo WeibelPinho, Roberto Rosasinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFJFinstname:Universidade Federal de Juiz de Fora (UFJF)instacron:UFJFTHUMBNAILIrradiação de polímeros com feixe de elétrons.pdf.jpgIrradiação de polímeros com feixe de elétrons.pdf.jpgGenerated Thumbnailimage/jpeg1599https://repositorio.ufjf.br/jspui/bitstream/ufjf/9262/4/Irradia%c3%a7%c3%a3o%20de%20pol%c3%admeros%20com%20feixe%20de%20el%c3%a9trons.pdf.jpg791aeff1f35ccc0a9ab9f4b6533b4270MD54ORIGINALIrradiação de polímeros com feixe de elétrons.pdfIrradiação de polímeros com feixe de elétrons.pdfapplication/pdf287689https://repositorio.ufjf.br/jspui/bitstream/ufjf/9262/1/Irradia%c3%a7%c3%a3o%20de%20pol%c3%admeros%20com%20feixe%20de%20el%c3%a9trons.pdfdccdb91799dcb7ea010b8b273d1755dcMD51LICENSElicense.txtlicense.txttext/plain;
