Abstract：
Assuming a single proton 2p state structure of ¹³N, we study the halo like structure of ¹³N by calculating proton ¹³N 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 ¹³C, 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 ¹³C halo like structure and its experimental verifications, our present results evidently show that a possible halo like proton skin of ¹³N in ground state most likely exists. Therefore, an immediate experimental measurement of p-¹³N elastic scattering at the energy of 1 GeV is urgently demanded.
