Basis-generator-method study of ionization and fragmentation of water molecules by multiply-charged ion impact

In a recent series of publications we have described the adaptation of the basis generator method (BGM), originally developed for ion-atom collisions, to molecular targets and have reported on results for proton and He$^{+}$-ion impact on H$_2$O molecules [1]. The microscopic collision calculations were complemented with a semi-phenomenological fragmentation model [2], which in contrast to previous models takes multiple electron removal processes into account. This turned out to be crucial for obtaining reasonable agreement with experimental data for the production of singly charged fragment ions. In this contribution, we report on results obtained from using the same methodology for bare helium, lithium, and carbon ion impact on H$_2$O in the 20--5000 keV/amu regime and compare them with experimental data and previous calculations where available. In addition, we will discuss the usefulness of ternary plots [3] to provide a somewhat more general view on fragmentation in ion-water-molecule collisions. \\[4pt] [1] M. Murakami {\em at al}, Phys.
