By equating the decay width associated with the decay of the dipole states into the compound states, to the spreading width of the giant dipole resonance, a limiting excitation energy for the observation of the GDR can be calculated. Evaluating the temperature dependence of ΓCN↓ (cf., e.g., Pühlhofer (1977)) and making use of the fact that ΓD↓ is independent of temperature (cf. Chs. 9 and 10 and also the previous section) one obtains, in the case of 110Sn, Elim*≈250 MeV, in overall agreement with the experimental findings.

The decay width is related to the life time of the TNI. To know which pathway the TNI will follow in the process of the decay we will need to know the lifetime of the individual ions. Unfortunately, in our method we get the total decay width and hence the life time. Hence, predicting the decay channel TNI will follow will not be possible. Computing the different dissociation pathways contributing to the resonances are beyond the scope of this work. In order to calculate the pathways, time-dependent nuclear wavepacket (which can be an impure state) calculations using the non-Hermitian quantum mechanics are needed which requires the entire resonance complex potential energy surface. An example to such a procedure can be found in the work by Ben-Asher and Moiseyev [56,57]. Table 1 also provides a comparative study of the resonance energies and symmetries computed theoretically in this present work and experimental work by Jana and Nandi [17].
