The MKS atomic polarizability α in cubic meters is given by [formula omitted], where [formula omitted] is the (more commonly tabulated) cgs polarizability in cubic centimeters.

Compare Ref. 6, Eq. (1-8-5), and Ref. 12, Eq. (II-11-9).

It should be noted that while there is no power absorption from the static electric fields, the static fields may affect the conditions of power absorption.
-
For instance, components of the static fields which result in a net radial electric force when averaged over the ion orbit will change the resonant frequency of an ion.

These conditions are (a) that the alternating electric field intensity may be assumed uniform throughout the analyzer and zero elsewhere; (b) that the drift velocity and residence time are the same for all ions of a given mass and are known.

The steady state is defined by [formula omitted] where ξ is any of the collision frequencies in Eq. (26) and t is the time that the ion has been absorbing energy.

References 11 and 24 give expressions for reactive ions which are valid at resonance [formula omitted] for each ion which were derived by assuming [formula omitted] is the power absorption per ion at resonance.

This expression is obtained from Eq. (20) by applying the limit [formula omitted] Reference 19 gives the analogous expressions for the full line shape derived from Eq. (20).

Both Refs. (11) and (24) give power absorption expressions in terms of second-order rate constants rather than in terms of first-order rate constants as is done in the present work.

Equation (36) may easily be extended to the situation where more than one secondary ion is formed from the primary ion by equating [formula omitted] to [formula omitted] where [formula omitted] is the first-order rate constant for the formation of the jth secondary ion.

Of course this value for the intensity ratio error is characteristic of the particular illustrative example as given.

In general the error will be somewhat different for other systems.
