摘　　要：Nowadays,the study on the deformation of heavy nuclei and super-heavy nuclei (SHN) is a hot subject in nuclear physics.A number of heavy nuclei and SHN around 270Hs have already beenNowadays, the study on the deformation of heavy nuclei and super-heavy nuclei （SHN） is a hot subject in nuclear physics. A number of heavy nuclei and SHN around 270Hs have already been observed experimentally. The theoretical study of deformed SHN suggests that 270Hs is a doubly magic deformed nucleus. However, there is no experimental evidence for the deformed shapes of the above-mentioned nuclei. Finding such evidence would be of great importance. It would confirm the unexpected structure of these SHN. In 2001, Sobiczewski et al. proposed to observe the refined structure of the decay to a rotational spectrum of the daughter nucleus to extract information on heavy nuclei and SHN deformation.
