QUANTUM WAVEPACKET DYNAMICS ON THE BH 1-SIGMA+ STATES

We investigate the dynamics of the ground state and the first three si nglet 1SIGMA+ excited states of BH using the split-operator method. Ab initio calculations show that these states have strong non-adiabatic couplings, resulting in a complex topology of avoided crossing regions and double well potentials. We attempt to find a method to populate t he second minimum of B 1SIGMA+ enabling experimental observation of it s vibrational states.
