Abstract In hot plasma creation by heavy-ion-beam irradiation, K-shell ionization of target atoms is accompanied by outer-shell ionization by ion impacts. This process is called multipleionization. In the case that multipleionization by incident heavy ions is comparable to single ionization by plasma electrons, an ionization degree of target atoms is enhanced, giving misleading estimation of plasma temperature if the processes are not considered in plasma diagnostics. In this study, Kα spectra are calculated with and without the multipleionization by solving population kinetics under collisional radiative equilibrium (CRE), and plasma conditions where the multipleionization has a large contribution are clarified.
