  Through the triple-alpha process practically all of the carbon in our
universe is synthesized as the ash of helium burning in red giants. The
triple-alpha process proceeds trough the ground state of 8Be and though the
02+-state in 12C. We investigate the dependence of 02+-state and the production
of carbon as a function of the strength of the underlying nucleon-nucleon
interaction. This is performed by using the complex scaling method in a
microscopic cluster model.
