Con solo 23 a\u00f1os, junto al cient\u00edfico ingl\u00e9s Cecil Frank Powell y al italiano Giuseppe Occhialini, descubri\u00f3 una part\u00edcula en el interior del n\u00facleo at\u00f3mico que asegura la cohesi\u00f3n del \u00e1tomo: el mes\u00f3n pi.<\/p>\n\n\n\n<p>Por aquel entonces, los cient\u00edficos de todo el mundo se preguntaban c\u00f3mo se manten\u00edan unidos los protones en el n\u00facleo del \u00e1tomo. Su inter\u00e9s por estos temas le llev\u00f3 a trasladarse a Inglaterra, donde trabaj\u00f3 en el Laboratorio de la Universidad de Bristol junto a Giuseppe Occhialini y Cecil Powell (Premio Nobel de F\u00edsica en 1950). Juntos descubrieron una nueva part\u00edcula at\u00f3mica, el mes\u00f3n pi o pi\u00f3n, que se desintegra en un nuevo tipo de part\u00edcula, el mes\u00f3n o <a href=\"https:\/\/rinconeducativo.org\/es\/recursos-educativos\/jack-steinberger-premio-nobel-de-fisica-por-el-descubrimiento-del-muon\/\">mu\u00f3n<\/a>. Esto supuso el comienzo de una nueva \u00e1rea de investigaci\u00f3n: la f\u00edsica de part\u00edculas.<\/p>\n\n\n\n<p>En 1947, con el objetivo de adentrarse en la que fuera su principal l\u00ednea de investigaci\u00f3n en torno al \u201cestudio de los rayos c\u00f3smicos\u201d, Lattes parti\u00f3 hacia Chacaltaya, uno de los picos m\u00e1s altas de los Alpes bolivianos, donde los rayos provenientes del espacio eran m\u00e1s intensos. All\u00ed, a m\u00e1s de 5.000 metros de altura, expuso placas fotogr\u00e1ficas a la acci\u00f3n de los rayos c\u00f3smicos, logrando comprobar experimentalmente la existencia de mesones pesados o piones.<\/p>\n\n\n\n<p>Si quieres saber m\u00e1s sobre este cient\u00edfico, haz clic en: <a href=\"https:\/\/rinconeducativo.org\/en\/recursos-educativos\/cesar-lattes-codescubridor-meson-pi-o-pion\/\" target=\"_blank\" rel=\"noreferrer noopener\">C\u00e9sar Lattes<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>8 de marzo de 2005 \u2013 Fallece C\u00e9sar Lattes, codescubridor del mes\u00f3n pi o pi\u00f3n<\/p>\n","protected":false},"author":1088,"featured_media":33666,"template":"","meta":{"_acf_changed":false,"footnotes":""},"tags":[6255,8183],"mes":[7124],"clasificacion_anterior":[],"class_list":["post-33664","re_efemeride","type-re_efemeride","status-publish","has-post-thumbnail","hentry","tag-atomos","tag-radiacion","mes-marzo"],"acf":{"fecha":"20050308"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.8 -
