| Outline of Final Research Achievements |
Neutorinoless double beta decay requires Majorana nature of neutrino and various experiments search for this decay. Next target of experiments is to search for inverted hierarchy; its target half life reaches to 10 to the power 26-27 year. For a large liquid scintillator experiment, improvement of energy resolution is quite important.
We developed linear alkyl benzene based liquid scintillator with high light yield. Purification method is evaluated and its light yield is 1.52 times higher than current liquid scintillator.
