  An important aspect of solar energetic particle (SEP) events is their source
populations. Elemental abundance enhancements of impulsive SEP events,
originating in presumed coronal reconnection episodes, can be fitted to steep
power laws of A/Q, where A and Q are the atomic mass and ionic charge. Since
thermal electron energies are enhanced and nonthermal electron distributions
arise in the reconnection process, we might expect that ionic charge states Q
would be increased through ionization interactions with those electron
populations during the acceleration process. The temperature estimated from the
SEPs corresponds to the charge state during the acceleration process, while the
actual charge state measured in situ may be modified as the SEPs pass through
the corona. We examine whether the temperature estimation from the A/Q would
differ with various kappa values in a kappa function representing high-energy
tail deviating from a Maxwellian velocity distribution. We find that the
differences in the A/Q between a Maxwellian and an extreme kappa distribution
are about 10-30%. We fit power-law enhancement of element abundances as a
function of their A/Q with various kappa values. Then, we find that the derived
source region temperature is not significantly affected by whether or not the
electron velocity distribution deviates from a Maxwellian, i.e., thermal,
distribution. Assuming that electrons are heated in the acceleration region,
the agreement of the SEP charge state during acceleration with typical active
region temperatures suggests that SEPs are accelerated and leave the
acceleration region in a shorter time than the ionization time scale.
