安定核から遠く離れた不安定原子核の核構造を調べるうえで、線核分光実験は非常に強力な手法である。しかし、生成量が極めて少ない超重核の核分光実験は極めて困難であり、実験手法や測定対象が極めて制限される。そのような制限の中で、どのような実験手法が適用可能であり、どのような核種が測定可能であるかを示し、それらの実験から超重核の核構造に関してどのような情報が得られるかを議論する。

-ray spectroscopy is very powerful to study nuclear structure of unstable nuclei located far away from the stable nuclei. However, spectroscopic studies of superheavy nuclei are extremely difficult because their production rates are extremely low. Thus, experimental techniques applicable to the superheavy nuclei and nuclei to be able to studied experimentally are strictly restricted. Under such restricted situation, I discuss which techniques are applicable, which nuclei can be measured, and what information can be obtained to clarify nuclear structure of superheavy nuclei.
