【摘要】 在“d-d四体破裂反应的单态氘中间过程(I)”的研究基础上选择可以减小运动学模糊效应的几何条件,在相应于θ_c=90°和θ_c=64°的实验室角度上测量d-d反应形成的单态氘破裂时发出的两个质子的二维能谱,在预期的能区内观测到明显的计数增长。实验测得单态氮的破裂能E_B=(52±21)keV。更多还原

【Abstract】 At C. M. angles 90°and 64°two-dimensional spectra of protons emitted from sing-let deuterons were measured under such geometry where the kinematic ambiguty wassmall. From the data it is obtained that the breakup energy E_B of the singlet deuteronstate is (52+21) keV.更多还原
