IMPLANTATION OF REACTIVE AND UNREACTIVE IONS IN SILICATES AND ICES

We present selected results of a series of experiments, performed in o ur laboratory, on the implantation of similar or equal to 1 keV/amu re active (H, C, N, O) and unreactive (He, Ar) ions into silicon, silicat es and frozen gases. The purpose to irradiate Che last two samples, is to simulate solar wind ion implantation on planetary objects. In part icular we investigated on the possibility of producing chemical bonds between the projectile and the target atoms searching for the appearan ce of characteristic IR bands. When the impinging ion is reactive (H, C, N, O) we found several cases of newly produced molecular species th at include the projectile.
