Abstract
High quality measurements in respect to accuracy, resolving power and sensitivity using negative osmium ions confined in ion traps will contribute to answer questions in modern fundamental physics. A proposed system to carry out these measurements would require a laser desorption ion source, and an ion-trap system. Following the recent laser spectroscopy investigations at the Max-Planck Institute for Nuclear Physics in Heidelberg, the goals of the proposed system should focuss on the laser cooling of negative osmium ions since such a system could be used to cool antiprotons to very low temperatures via collisions (sympathetic cooling) for efficient antihydrogen formation in its ground state. Furthermore, together with rhenium ions, the confinement of osmium ions in a Penning trap is important to determine the mass difference 187Re-187Os, and therefore the Q-value in the decay of 187Re (T 1/2 = 4×1010 years) with unprecedented accuracy. This Q-value is an important constraint for the determination of the mass of the electron antineutrino as aimed by the international MARE collaboration. In this paper several mechanisms are considered for the preparation of the negative ions in order to apply laser cooling.
