The ejected electron is called a photoelectron. The resultant vacancy in the K-shell can be filled by an electron from another shell and a K-fluorescent x-ray is generated from the transition.\u003c/p\u003e\u003cp\u003eAdapted from\u0026nbsp;\u003ca href=\"https://en.wikibooks.org/wiki/Basic_Physics_of_Digital_Radiography\"\u003eBasic Physics of Digital Radiography\u003c/a\u003e\u0026nbsp;by\u0026nbsp;Kieran Maher,\u0026nbsp;with author's permission (License:\u0026nbsp;\u003ca href=\"https://creativecommons.org/licenses/by-sa/3.0/\"\u003eCreative Commons\u0026nbsp;BY-SA 3.0\u003c/a\u003e).\u003c/p\u003e","id":636,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/2748","nextQuestionPath":"/articles/coherent-scattering/questions/629","relatedArticles":[{"id":30308,"title":"Compton effect","link":"/articles/compton-effect?lang=us"},{"id":29684,"title":"Photoelectric effect","link":"/articles/photoelectric-effect?lang=us"},{"id":31661,"title":"Pair production","link":"/articles/pair-production?lang=us"}],"alsoUsedIn":[],"stem":"\u003cp\u003eThe type of x-ray interaction with matter in which all of the energy of the incident photon is expended in dislodging a bound electron is called...\u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/636"}],"attemptsPercentages":[{"alternativeId":"3186","percentage":4},{"alternativeId":"3184","percentage":14},{"alternativeId":"3185","percentage":4},{"alternativeId":"3183","percentage":76},{"alternativeId":"3294","percentage":2}],"promptToLogin":false,"questionManager":false,"articleId":"coherent-scattering"}
