Qicun Shi explains to Sabre KaisSabre Kais, Associate Professor of Chemical Physics in Purdue University correlation effects in scattering of an electron on lithium-like atom with a variable nuclear charge slightly above two after a lecture of Imad LadadwaImad's link page about ionization cross sections at internal meeting of the quantum chemistry group. Purdue University, West Lafayette, Indiana
The image presents a scene from a lecture or discussion within a research group, specifically focusing on correlation effects in scattering of an electron on lithium-like atoms with varying nuclear charges.
**Composition and Content**
* The top half of the image features two photographs side by side.
+ The left photograph shows Qicun Shi writing on the chalkboard with his right hand while holding a piece of white chalk in his left.
+ The right photograph displays Sabre Kais' arm and hand, which he is using to point at something on the chalkboard.
* The bottom half of the image presents a single photograph showing Qicun Shi standing in front of the chalkboard, facing to the side and looking up toward the upper left corner.
**Color Scheme**
The photographs have a distinct color scheme, with brownish hues throughout, likely due to the use of film or printing techniques from the past. The photographs have been scanned and digitally enhanced, resulting in a somewhat faded appearance.
**Overall Impression**
The image conveys an atmosphere of intellectual engagement among members of the research group. Qicun Shi is actively teaching or explaining concepts related to correlation effects in scattering of electrons on lithium-like atoms with variable nuclear charges, while Sabre Kais appears engaged and attentive, pointing at something on the chalkboard. – AI vision
🇨🇳 中文描述 / Chinese Description
Qicun Shi向Sabre Kais解释了碰撞一个电子时,在锂原子核带正电荷略高于2的情况下的相关影响。这是Imad Ladadwa在量子化学小组内部会议上讲授有关离子化横截面积后拍摄的。 1999年10月,美国印第安纳州西拉法叶的普渡大学。 图片描绘了一个研究小组中的讲座或讨论场景，重点关注在锂原子核电荷变化情况下碰撞电子时的相关影响。
**构成与内容** * 图片上半部分有两幅照片并排显示。其中， * 左边一张照片展现了Qicun Shi用右手在黑板上写字，同时在左手拿着白色毛巾。 * 右边一张照片显示Sabre Kais的手臂和手指向黑板上某处。 * 图片下半部分是一幅单独照片，Qicun Shi站在黑板前面，侧面看着上方左角。 **颜色方案** 这些照片有明显的色彩方案，整体呈现出棕色调，很可能是由于过去使用过胶片或打印技术造成。这些照片已被扫描并进行数字增强，因此看起来有点褪色。 **总体印象** 这张图片表现了研究小组成员之间智力互动的氛围。Qicun Shi正在积极讲授或解释相关影响时碰撞电子在锂原子核上带正电荷略高于2的情况下的相关效应，而Sabre Kais则专心致志并注意到黑板上某处。. – Chinese translation
