Abstract

We report on a measurement of elastic electron scattering on argon performed with a novel cryogenic gas-jet target at the Mainz Microtron accelerator MAMI. The luminosity is estimated with the thermodynamical parameters of the target and by comparison to a calculation in distorted-wave Born approximation. The cross section, measured at new momentum transfers of 1.24 \(\hbox {fm}^{-1}\) and 1.55 \(\hbox {fm}^{-1}\) is in agreement with previous experiments performed with a traditional high-pressure gas target, as well as with modern ab-initio calculations employing state-of-the-art nuclear forces from chiral effective field theory. The nearly background-free measurement highlights the optimal properties of the gas-jet target for elements heavier than hydrogen, enabling new applications in hadron and nuclear physics.

新型气体喷射靶40Ar（e, \(\hbox {e}^{\prime }\)）弹性散射截面的测量

本文报道了在美因茨微波加速器MAMI上用新型低温气体喷射靶对氩气弹性电子散射的测量。利用目标的热力学参数，并与畸变波玻恩近似的计算结果进行比较，估计了目标的光度。在1.24 \(\hbox {fm}^{-1}\)和1.55 \(\hbox {fm}^{-1}\)的新动量转移下测量的横截面与之前用传统高压气体靶进行的实验以及采用手性有效场理论中最先进的核力的现代从头计算相一致。几乎没有背景的测量突出了比氢重的元素的气体喷射目标的最佳特性，使强子和核物理学中的新应用成为可能。
