Abstract
The electron temperature in a Li2CO3 ablative capillary discharge has been estimated on the base of soft x-ray spectral line intensity measurements an d of evaluations of steady-state ionization and population fractions for th e mixture of lithium, carbon and oxygen. The discrepancy in the peak temper atures, estimated from spectral measurements and calculated by one-dimensio nal NM and time dependent collisional-radiative codes, is explained by an i nitial overheating of the plasma electrons.
