在于韦斯屈莱大学使用反冲分离器RITU和JUROSPHERE II阵列对252 No的激发态进行了束内研究。这是在束流实验中研究的第二个transfermium核。自旋20的水平被填充，并与254号的水平进行比较。在对应于自旋16的200 keV/预测的频率下观察到上弯。我们还使用了一个改进的系统学连接的最低的2+状态的能量与它的半衰期，并发现2 5 2，2 5 4 No的变形略大于先前假设的。
An in-beam study of excited states in the transfermium nucleus 252 No has been performed using the recoil separator RITU together with the JUROSPHERE II array at the University of Jyväskylä. This is the second transfermium nucleus studied in an in-beam experiment. Levels up to spin 20 were populated and compared to levels in 254 No. An upbend is seen at a frequency of 200 keV/ħ corresponding to spin 16. We also use an improved systematics to connect the energy of the lowest 2+ state with its half-life and find that the deformation of both 2 5 2, 2 5 4 No is slightly larger than previously assumed.
