    A two state model study of photo-detachment dynamics driven by an optimally designed polychromatic field: A simulated annealing based optimisation
    (International Journal of Quantum Chemistry, 2021) Talukder S.;Seal D.;Naskar P.;Chaudhury P.;Ghosh S.
    The surfaces of urn:x-wiley:00207608:media:qua26676:qua26676-math-0001 and F2 are two well separated surfaces modeled by two Morse potentials. In presence of a field, these two surfaces couple and transition from urn:x-wiley:00207608:media:qua26676:qua26676-math-0002 to F2 takes place resulting in the detachment of an electron. We have applied Simulated Annealing (SA) technique to design the polychromatic field which results in ∼ 95% probability of photo detachment (Pd). Also we have designed a field to achieve photo detachment followed by dissociation of FF bond with nearly 38% dissociation probability. F2 being a homo nuclear diatomic molecule, promotion to the continuum states by directly exciting it from its ground vibrational state is an impossibility and our method appears to be a feasible solution if the target is to break the FF bond.
