抄録
A total absorption detector, which is composed of a through-hole type HPGe detector coupled with a surrounding annular anti-Compton BGO detector, has been developed for beta(-)-decay energy (Q(beta)) measurements of nuclei far off from the P-stability line. This detector can measure radiations with an almost 4 pi solid angle by putting radioactive sources in the middle of the HPGe detector and also can suppress the scattered photons with the anti-Compton BGO scintillation detector. The systematic uncertainty was determined to be 30 keV by measuring 19 nuclei having Q(beta)s between 3 and 8 MeV by means of conventional square-root plot analysis. The Q(beta)'s of mass-separated fission products La-147 and La-148 were successfully determined to be 5366(40) and 7732(70) keV, respectively.
