The 13N+p elastic resonance scattering has been studied at the secondary radioactive beam facility of CIAE in inverse kinematics via a thick-target method. The excitation function for the 13N(p,p) sca...
13N的一个可能的类晕的质子2p态
原子核结构 原子核的类晕现象 高能散射 Glauber理论
2009/6/12
假设13N是单粒子的2p态的结构,用Glauber多重散射理论计算了1GeV的质子在13N上弹性散射的微分截面,研究了13N的类晕结构.与13C的情况不同,虽然目前还没有关于p-13N弹性散射微分截面的实验材料与我们的理论结果相比较,但是这个理论结果可以作为对未来的实验测量工作的一个指导,特别是对兰州近代物理研究所的晕核实验研究工作有参考和指导价值.参照先前我们对13C晕核结构的理论预言和进而的...
天体物理重要反应13N(p,γ)14O的实验研究
高温CNO循环 渐进归一化系数 S因子
2009/3/24
13N(p,γ)14O是高温CNO循环中的关键反应,对恒星能量产生机制及其演化的研究具有重要意义。利用北京HI-13串列加速器次级束流线产生的13N放射性束测量了质心系能量为8.9MeV的13N(d,n)14O反应的角分布,导出了14O基态渐进归一化系数(ANC)为(29.4±5.3)fm-1。此外,使用镜像核的电荷对称性,通过分析13C(d,p)14C反应的角分布,导出了与实验一致的14O基态质...
Uptake of HNO3 to deliquescent sea-salt particles: a study using the short-lived radioactive isotope tracer 13N
HNO3 deliquescent sea-salt particles short-lived radioactive isotope tracer 13N
2009/3/12
The uptake of HNO3 to deliquescent airborne sea-salt particles (RH = 55%, P = 760 torr, T = 300 K) at concentrations from 2 to 575 ppbv is measured in an aerosol flow tube using 13N as a tracer. Small...
