His announcement drew little attention at the time, but six years later German astronomer Johann Elert Bode popularized the sequence, now known as the Titius-Bode law. Both scientists drew atten-tion to a notable gap in the numbers.

The sputtering behaviour of components in different devices such as in ion thruster engines, in fusion plasma chambers and in fluorescent lamps is of great importance in order to model their long-term performance, because the degradation of components is determined by the ion–surface interactions.

In particular, the sputtering mechanism for light ions received attention from attempts at understanding the erosion of planetary surfaces by the solarwind23 or investigations of the magnetic confinement of hydrogen plasmas for fusion reactors.4 However, little is known about very low-energy sputtering by heavy.

In this work a modified Freeman Ion source, used for ion sputtering, is designed and constructed. The choice of this ion source was based on its remarkable success in the semiconductor industry employing ion implantation : Hikmat A Hamad, Nibras F Ali, Haitham M Farok.

Using this sensitive and level selective method, sputtered densities for Ca and Cr atoms in the electronic ground and excited metastable states have been investigated as a function of oxygen background by: Using molecular-dynamics simulation, we study the scattering and penetration of normally incident hyperthermal (5– eV) Ne, Ar, and Xe atoms off a Cu crystal.
