neutron number 【原子】(核內)中子數。

neutron star

Our results show that with the up to date experimental data , 13c can not sufficiently burn , the neutron number density decrease , the timescale of neutron source become long and these come into conflict with model of thermal pulse agb star 研究結果表明,在新實驗結果下, ’ 3c不能充分燃燒,中子數密度降低,中子源持續的時標變長,這與熱脈沖agb星的現有模型出現矛盾。
