【 摘 要 】
Inour previous research, it has been demonstrated that inelastic processes in atom Rydberg-atom collisions, such as chemi-ionization and ($n-n'$) mixing, should be considered together. Here we will review the present state-of-the-art and the actual problems. In this context, we will consider the influence of the ($n-n'$)-mixing during a symmetric atom Rydberg-atom collision processes on the intensity of chemi-ionization process. It will be taken into account H(1s) + H*(ð‘›) collisional systems, where the principal quantum number is $n gg 1$. It will be demonstrated that the inclusion of ($n-n'$) mixing in the calculation, influences significantly on the values of chemi-ionization rate coefficients, particularly in the lower part of the block of the Rydberg states. Different possible channels of the ($n-n'$)-mixing influence on chemi-ionization rate coefficients will be demonstrated. The possibility of interpretation of the ($n-n'$)-mixing influence will be considered on the basis of two existing methods for describing the inelastic processes in symmetrical atom Rydberg-atom collisions.
