Avustralya \u00dcniversitesi’nde \u00e7al\u0131\u015fma y\u00fcr\u00fcten Cedric Simenel, “Biliminsanlar\u0131 uzun zamand\u0131r fisyon olay\u0131n\u0131n \u00e7ekirdek yap\u0131s\u0131nda meydana getirdikleri etkileri tahmin edebiliyorlard\u0131 ancak ger\u00e7ekte tam olarak neyin g\u00f6zlemlendi\u011fi a\u00e7\u0131klanam\u0131yordu” dedi ve ekledi: “Sim\u00fclasyonlar\u0131m\u0131z, \u00e7ekirdek k\u0131r\u0131lmadan \u00f6nce deformasyonun ger\u00e7ekle\u015fti\u011fini ve bir noktadan uzama meydana gelirken ba\u015fka bir noktadan da armut bi\u00e7imi al\u0131nd\u0131\u011f\u0131n\u0131 ve par\u00e7alanman\u0131n ba\u015flad\u0131\u011f\u0131n\u0131 ortaya koydu.”<\/p>\n
\u00c7ekirde\u011fin kendili\u011finden par\u00e7alanmas\u0131yla olu\u015fan fisyon, n\u00fckleer enerjiyi a\u00e7\u0131\u011fa \u00e7\u0131kar\u0131r. Bu s\u00fcre\u00e7, \u00f6zellikle de y\u0131ld\u0131zlar\u0131n patlamas\u0131nda veya n\u00f6tron y\u0131ld\u0131zlar\u0131n\u0131n \u00e7arp\u0131\u015fmas\u0131 gibi \u015fiddetli kozmik olaylarda da g\u00f6zlenir. Ancak \u00e7ekirdek yap\u0131s\u0131n\u0131n nas\u0131l par\u00e7aland\u0131\u011f\u0131, par\u00e7alan\u0131rken nas\u0131l bir form ald\u0131\u011f\u0131 \u015fimdiye kadar bilinmiyordu.<\/p>\n
B\u00fcy\u00fck \u00e7ekirdek yap\u0131s\u0131na sahip olan atomlar, e\u015fit say\u0131da proton ve n\u00f6trona sahip olacak par\u00e7alar halinde b\u00f6l\u00fcnmez. Yeni \u00e7al\u0131\u015fma bu durumun nas\u0131l olu\u015ftu\u011funu a\u00e7\u0131klamaya yard\u0131mc\u0131 oluyor. \u00c7al\u0131\u015fmada kullan\u0131lan sim\u00fclasyonlar, \u00e7ekirdeklerin k\u0131r\u0131lma an\u0131na gelene kadar gerildi\u011fi ve do\u011fal k\u00fcresel \u015fekilde de\u011fil armut bi\u00e7imi alarak par\u00e7aland\u0131\u011f\u0131n\u0131 g\u00f6stermekte.<\/p>\n
