摘要:

在长波长近似下,在同位旋零态之间禁止电偶极跃迁。在考虑$T = 1$贡献的$α+n+p$模型中,$α(d,γ)^6$ Li天体物理$S$因子与LUNA合作组的实验数据一致,不需要调整参数.用于避免$E1$跃迁在势模型中消失的精确质量处方在微观水平上是不成立的。

英文摘要:

At the long-wavelength approximation, electric dipole transitions are forbidden between isospin-zero states. In an $α+n+p$ model with $T = 1$ contributions, the $α(d,γ)^6$Li astrophysical $S$-factor is in agreement with the experimental data of the LUNA collaboration, without adjustable parameter. The exact-masses prescription used to avoid the disappearance of $E1$ transitions in potential models is not founded at the microscopic level.
