Capture of a particles by isospin-symmetric nuclei

The reaction rates for ct capture processes on self-conjugate nuclei in the mass range A = 20-40 have been investigated. The rates were calculated using the statistical model code NON-SMOKER taking into account isospin suppression rules. These theoretical predictions are compared with rates derived from the available experimental data about the ct capture reactions but taking also into account additional experimental information from different reaction channels populating the cu unbound states of the self-conjugate compound nuclei.
