The triple-alpha process and its anthropic significance

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.

Radiative capture on neutron rich nuclei

The $({\rm n},γ)$--cross sections for neutron--rich oxygen isotopes have been calculated in the direct capture model. The experimental data for ${^{18}{\rm O}}({\rm n},γ){^{19}{\rm O}}$ can be reproduced using this model. Compared to previous work the cross section for ${^{19-21}{\rm O}}({\rm n},γ){^{20-22}{\rm O}}$ are enhanced considerably by factors between four and 300.
