Abstract

It is pointed out that the accidentally resonant charge-exchange reaction, O⁺ + H⁰ ∼ O⁰ + H⁺, is an important mechanism for causing the loss of singly charged oxygen ions from oxygen-contaminated hydrogen plasmas. Results of a Monte Carlo simulation are presented which show that the fraction of oxygen lost because of charge exchange exceeds 1/3 when the parameters n_e∼ 10¹³ cm⁻³, n_H⁰∼ 10¹¹ cm⁻³ and T_e∼ 3 eV are attained. This process may be important in determining impurity losses from the edge plasmas of tokamaks.
