我们测量了入射能量在60 ~ 630 keV/u之间的$\text{p}+\text{He}$和${^{3}\text{H}\text{e}}^{+}+\text{He}$碰撞中各种电子末态的射弹散射角依赖性。我们发现明显的峰值结构中的散射角依赖的一些不同的捕获通道的比率。我们解释这作为实验证据，激发过程的目标是由横向动量转移，导致一个额外的弹丸偏转。
We have measured the projectile scattering-angle dependency for various electronic final states for single-electron capture in $\text{p}+\text{He}$ and ${^{3}\text{H}\text{e}}^{+}+\text{He}$ collisions at incident energies between 60 and 630 keV/u. We find pronounced peak structures in the scattering-angle dependence of some of the ratios of different capture channels. We interpret this as experimental evidence that an excitation process of the target is caused by a transverse momentum transfer that leads to an additional projectile deflection.
