Abstract

A systematic study of point proton radii along an isotopic chain provides insights into the impact of the extended neutron wavefunction on the protons. This work aims to measure the charge-changing cross section (

σ_{c c}

) for neutron-rich

{}^{23}N

, marking the first determination of its point proton root mean square radius, as well as the

σ_{c c}

for

{}^{21, 22}N

at beam energies around 250A MeV.

测量富中子氮同位素的电荷变化截面以确定其质子半径

通过对同位素链上的点质子半径进行系统研究，可以深入了解扩展中子波函数对质子的影响。这项工作旨在测量富中子N23的电荷变化截面（σcc），这标志着首次测定了其点质子均方根半径，以及N21,22在250A MeV左右束能量下的σcc。
