Fine-structure -decay spectroscopy of superheavy nuclei

Asai, Masato  

To investigate nuclear structure of superheavy nuclei experimentally, spectroscopic methods which can reveal level structure of ground- and excited states are the most effective. In particular, fine-structure -decay spectroscopy is expected to be a very sensitive method because spectroscopic information can be obtained only through -particle measurements. However, it is difficult to measure particles of superheavy nuclei with high energy resolution. Moreover, the observed energy spectra are significantly distorted by coincidence summing effects. I would like to demonstrate how we can overcome these difficulties, and how useful the fine-structure -decay spectroscopy is to investigate nuclear structure of superheavy nuclei.
