摘要：

Absolute cross sections for ionization of 1.5-10.0 keV/amu Rydberg helium atoms in principal quantum states 12 less than or equal to n less than or equal to 15 due to collisions with potassium have been measured. The data are compared with the free-electron cross section at equal velocity. Our results for the collisional ionization cross sections (sigma(i)) agree both in shape and absolute magnitude with the data available for the total electron-scattering cross sections(sigma(e)) and support recent theoretical models for ionization of Rydberg atoms with neutral perturbers.
