reaction cross section meaning in English
反应截面
Examples
- Wavepacket ; timedependent ; potential energy surface ; reaction cross section ; reaction rate constant ; ozone
波包含时势能面反应截面反应速率臭氧 - Due to the repulsive coulomb field , the effective impact parameter increases , and therefore the calculated reaction cross section decreases
库仑场的排斥效应使得核?核反应有效的碰撞参数增大，使计算的反应截面减小，同时这种修正的效应随能量增大而减小。 - Since in the few - body glauber theory the core and valence nucleons of a halo nucleus are treated separately , the obtained expressions of the reaction cross section , the nucleon removal cross section and the momentum distribution are all involved in multidimensional integrations
由于在少体近似glauber模型中晕核被分成核芯和晕核子来处理，所以得到的晕中国原子能科学研究院博士学位论文核散射反应截面、核子逃逸截面以及动量分布的计算公式均包含高重积分。 - Therefore we could carry out numerical calculations and obtain the reaction cross section , the nucleon removal cross section and the momentum distribution in the scattering of a halo nucleus with any types of density distributions . we compare the reaction cross sections calculated in the few - body glauber theory and the optical - limit glauber theory
进一步对27p 、 28p反应截面的研究分析表明，考虑核芯2751的增大可以很好解释实验测量得到28p反应截面的增大，而要解释27p反应截面的异常增大，需要同时考虑核芯2 “ si增大和具有非常弥散空间分布的2s ， ， :态晕核子。 - It includes three steps : first , the experimental data in exfor format is evaluated . then , the optical potential parameters are got by using the code apom94 , and the direct inelastic discrete energy level reaction cross sections and angular distribution of every isotopes are got by using the code dppm . thus the ultimate commended data , which coincide with each other , can be obtained by using code nunf
其具体过程是先对exfor实验数据进行评价，给出实验数据评价值，然后，利用程序apom94计算光学位，利用dppm程序计算直接非弹分立能级反应截面和角分布，在此基础上，利用nunf理论计算程序获得各同位素本身数据以及各同位素与天然元素数据自洽的最终推荐值。
