在270 MeV下分析dd-> 3 Hen反应中的幂Ayy、Axx、Axz和Ay
Analyzing powers Ayy, Axx, Axz and Ay in the dd->3Hen reaction at 270 MeV
摘要：
在Td= 270 MeV时，在0 - 110度的角度范围内，以c.m.给出了在小角度处观察到的张量分析功率Ayy、Axx和Axz的负号清楚地表明了对3 He波函数的D和S波分量的比率的敏感性。然而，用标准的~ 3 He波函数计算单核子交换时，不能再现张量分析幂随角的变化。
英文摘要：
The data on the tensor Ayy, Axx, Axz and vector Ay analyzing powers in the dd->3Hen obtained at Td= 270 MeV in the angular range 0 - 110 degrees in the c.m. are presented. The observed negative sign of the tensor analyzing powers Ayy, Axx and Axz at small angles clearly demonstrate the sensitivity to the ratio of the D and S wave component of the 3He wave function. However, the one-nucleon exchange calculations by using the standard 3He wave functions have failed to reproduce the strong variation of the tensor analyzing powers as a function of the angle in the c.m.
