The author previously derived a semiempirical formula for determining the ionization coefficient beta for the collision of meteor atoms with atmospheric atoms and molecules: beta = 4.70 x 10 to the -15th power v squared (1-Ei/E), where E and v are the kinetic energy and velocity of the meteoroid and Ei is the ionization potential of meteor atoms. This formula is used for computing beta for the mean chemical composition of meteor bodies. Solution of many problems in meteor astronomy, however, require a knowledge of the ionization coefficient for different chemical elements making up meteor matter. The cited formula is used in computing the values of the ionization coefficient for the main components of meteor matter. Computations of beta for the usual atoms were made for meteor velocities 10 to /0 km/sec. Special attention was given to atoms with numbers up to Z = 30. There is a definite regularity in the behavior of the curves of the dependence of the ionization coefficient on atomic number Z.
