铜的L壳层x射线是通过将25到1700 kev的质子阻挡在厚靶上而产生的。在${L}_{\ mathm {III}}$壳层中产生初始空位的X射线用吸收技术分离出来。给出了总$L$-壳层的x射线产率，以及${L}_{\ maththrm {III}}$壳层的产率、产率和电离截面。将玻恩近似与实验电离截面进行比较，发现在整个轰击能量范围内，玻恩近似始终较高。
$L$-shell x rays of copper were produced by stopping 25- to 1700-keV protons in a thick target. X rays associated with the production of initial vacancies in the ${L}_{\mathrm{III}}$ shell were isolated by an absorption technique. Total $L$-shell x-ray yield is presented, as well as yield, production, and ionization cross sections for the ${L}_{\mathrm{III}}$ shell. The Born approximation is compared with the experimental ionization cross section and is found to be consistently high over the whole range of bombarding energies.
