4. Outlook - control of the Na3** collision complex
Upon achievement of the desired energy resolution of the ion imaging, it will be implemented to study the mechanisms of the DCT process (2). In fact, the Na2(v") + Na**(nl) collisions leading to the formation of a highly excited complex is an interesting process to study due to various ionisation channels through which the complex can decay:
Threshold energy [eV]
Na2 (X 1Sg+ ,v??) + Na** (nl)
Na- + Na+ + Na
Na2 + Na++ e-
Na2++ Na + e-
Na2- + Na+
Na2++ Na -
The threshold energies are given in terms of total (electronic, vibrational, and rotational) energy deposited in the Na2 + Na colliding system. Besides the manipulation of the ionisation channels by control of the electronic and vibrational excitation of atoms and molecules, also schemes for coherent laser control are thinkable.
