这时正是1945年,实验室的人由国防工作转回来的越来越多.他们要恢复回旋加速器作研究,催了好几次,最后不得不拆掉α谱仪.所以,上面所介绍的现象未能深入观察、研究,始终未得到答案.这是我不满意的一个方面.直到现在想到这事,心里仍很不安,因为问题没有解决,不知是什么东西.我是1943年秋天到的普林斯顿.当时除我所在的组外,科学研究差不多都停顿了,有经验的教师基本上都出去了.教学还有一点,我有时候代莱德伯上核物理课.到45—46年间,一切又开始恢复正常.这个阶段有一个人找我好几次,说现在有一个单位对α能谱的研究工作很感兴趣.不仅天然放射物可放出α射线,人工产生的物质也可以放出α粒子,都需要测量它们的能谱.这个工作可以作一辈子,或许还完不了,待遇也很好.问我是否有兴趣去工作,而且可以把当时正在用的一套仪器带去. It was at this time that more and more people in the laboratory were turned back from national defense work in 1945. They tried to resume the cyclotron for research, urging them several times and eventually having to disassemble the alpha spectrometer, so the above introduction The phenomenon was not observed in depth, the study has not been answered. This is one aspect I am not satisfied with. Until now think of it, my heart is still uneasy, because the problem is not solved, I do not know what I was in the fall of 1943 Princeton. At that time, except for the rest of my group, scientific research was almost halted, and experienced teachers were basically gone. And there was a little teaching, and sometimes I took De Lade on a nuclear physics course. Between 45 and 46 years, Everything began to return to normal one person at this stage to find me several times, saying that now there is a unit interested in the work of α-spectrum research.Not only emit natural radiation α rays, artificially generated substances can release α particles, Need to measure their energy spectrum.This work can be a lifetime, maybe not finished, the treatment is also very good.I asked if I am interested in working, and can bring a set of instruments was being used.
