Abstract

The decay cross sections of both spherical and deformed 26−29Al* formed through the entrance channels 16O+ 10B, 16O+ 11B, 18O+ 10B, and 18O+ 11B, respectively, have been calculated. The calculations are performed by considering the Coulomb plus proximity potential as interacting potential, for different ECM values. The computed light particle (LP) production cross section was found to be in good agreement with the experimental data, which made us to extend the studies on the total decay cross section, \(\sigma_{{{\text{Total}}}}\); IMF cross section, \(\sigma_{{{\text{IMF}}}}\); and LP cross section, \(\sigma_{{{\text{LP}}}}\) for the decay of 26−29Al* formed through the same entrance channels for ECM values other than the values obtained in experiments. Thereby, we expect our predictions on \(\sigma_{{{\text{Total}}}}\), \(\sigma_{{{\text{IMF}}}}\), and \(\sigma_{{{\text{LP}}}}\) for the decay of 26−29Al* may be of great use for further experimental studies. The least standard deviation of predicted logarithm of light particle cross section shows that our predictions are better than dynamical cluster-decay model predictions in both spherical and deformed cases.
