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 Be and though the 02+–state in C. 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 perform...

I discuss three issues relevant to solar neutrino flux measurements: cross section uncertainties in pp chain reactions, uncertainties in the GALLEX/SAGE response to 7 Be and 51 Cr neutrinos, and the implications of helioseismology for nonstandard suns with mixed cores. A few comments are also offered on νe ↔ ντ oscillations, cosmologically interesting neutrino masses, and recent proposals for s...

A method is presented for numerical implementation of the extended TDHF theory in which two-body correlations beyond the mean-field approximation are incorporated in the form of a quantal collision term. The method is tested in a model problem in which the exact solution can be obtained numerically. Whereas the usual TDHF fails to reproduce the long time evolution, a very good agreement is foun...
