摘要
An in-beam study of excited states in the transfermium nucleus No-252 has been performed using the recoil separator RITU together with the JUROSPHERE II array at the University of Jyvaskyla. This is the second transfermium nucleus studied in an in-beam experiment, Levels up to spin 20 were populated and compared to levels in No-254. An upbend is seen at a frequency of 200 keV/(h) over bar 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 die deformation of both No-252,No-254 is slightly larger than preciously assumed.
