^(13)N的一个可能的类晕的质子2p态(英文)

A Possible Halo Like Proton 2p States of ^(13)N

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实验证实 ,本文的计算结果清楚地表明 :13N可能存在着一个类晕的质子皮结构 .因此 ,实验上测量p - 13N弹性散射的微分截面就是当前需要马上进行的一个实验研究工作 .

Assuming a single proton 2p state structure of 13 N, we study the halo like structure of 13 N by calculating proton 13 N elastic scattering at the incident energy of 1GeV in the framework of Glauber multiple scattering theory. The theoretical prediction of the differential cross section is obtained. Unlike 13 C, there are no experimental data available at present to examine this prediction. However, the result could be a guide to the coming experimental measurement, particularly, for a possible experiment at the Institute of Modern Physics, the Chinese Academy of Sciences, Lanzhou, China. Recalling our previous theoretical prediction for 13 C halo like structure and its experimental verifications, our present results evidently show that a possible halo like proton skin of 13 N in ground state most likely exists. Therefore, an immediate experimental measurement of p? 13 N elastic scattering at the energy of 1 GeV is urgently demanded.
