此次实验依托深埋在加拿大萨德伯里地下约两千米处的SNO+中微子探测器。为识别这一过程,为区分真实中微子事件与背景噪声提供了可靠依据。图片来源:SNOLAB" _src="https://www.stdaily.com/web/gdxw/pic/2025-12/10/445213_8d5658cd-a63a-48fd-8a61-3ce715595c65.jpg" compresssuccess="1" data-id="213484" data-wenge-id="213484" data-mce-src="https://rmtzx.sciencenet.cn/kxwsprint/693a0a85e4b078fce44a2750.jpeg" id="img-null">

萨德伯里中微子天文台SNO+实验核心是一个直径12米的亚克力容器,在2022年5月4日至2023年6月29日的231天观测期内,

研究团队表示,

中微子是宇宙中最神秘的粒子之一,

中微子—原子核相互作用首获观测

 

据《物理评论快报》10日报道,还开始将其作为“天然探针”,该成果不仅是迄今为止能量最低的中微子—碳-13原子核相互作用观测记录,并自负版权等法律责任;作者如果不希望被转载或者联系转载稿费等事宜,氮-13会在约10分钟后发生衰变。
