【摘要】 用14MeV中子照射铀并借助于放化分离产生了²³⁵Th源,测得了β谱和γ谱,获得了²³⁵Th的β端点能量为1.44±0.04MeV,从而确定了其Q_β=1.47±0.07MeV.更多还原

【Abstract】 Sources of ²³⁵Th were prepared by 14MeV neutron irradiation of Uranium and radiochemical separation. The β-spectra and γ-spectra were measured. The endpoint energy for ²³⁵Th β-decay was obtained to be 1.44±0.04 MeV. Thus Q_β of ²³⁵Th was determined to be 1.47±0.07 MeV.更多还原
