我们提出了一种与时间相关的方法来研究雅可比坐标中低能反质子-氢原子碰撞中质量极化对共振能量和特定态质子形成的影响。与我们之前在形状坐标中忽略质量极化的计算相比，我们确认质量极化对质子形成的影响可以忽略不计。我们还计算了 坐标和雅可比坐标的共振能量。两次计算之间的谐振能量差异小于 4 meV。这也证实了即使在谐振区域质量极化效应也小到可以忽略不计。
We present a time-dependent method to investigate the mass polarization effect on the resonant energies ofand the state-specified protonium formation in low-energy antiproton–hydrogen-atom collisions in Jacobi coordinates. Comparing with our previous calculations in the-shaped coordinates by neglecting the mass polarization, we confirm that the mass polarization effect on the protonium formation is negligibly small. We also calculated the resonant energies ofin thecoordinates and Jacobi coordinates. The differences of the resonant energies between the two calculations are less than 4 meV. This also confirms that the mass polarization effect is negligibly small even in the resonant region.
