67. Ab initio calculations of light-ion reactions

Petr Navratil (TRIUMF)

Talk

We build a new ab initio many-body approach [1] capable of describing simultaneously both bound and scattering states in light nuclei, by combining the resonating-group method [2] with the ab initio no-core shell model [3]. In this way, we complement a microscopic-cluster technique with the use of realistic interactions, and a microscopic and consistent description of the nucleon clusters. We...

90. Interior and Exterior Contributions to Transfer Cross Sections

Ian Thompson (LLNL)

Talk

There has been much recent debate concerning what precisely is measured by (d,p) transfer reactions on nuclei. Do experiments measure spectroscopic factors or asymptotic normalization coefficients? This question is related to the relative importance for the transfer amplitudes of the interior and exterior contributions of the target bound-state wave functions. In order to probe this in more...

22. Microscopic calculation of the 3He(alpha,gamma)7Be reaction rate

Talk

We calculate the radiative capture cross sections for the 3He(a,g)7Be and the 3H(a,g)7Li reactions [1] in the fully microscopic Fermionic Molecular Dynamics approach [2] using a realistic effective interaction obtained in the Unitary Correlation Operator Method [3]. At large distances bound and scattering states are described by antisymmetrized products of 4He and 3He/3H ground states. At...

49. Overlap integrals, spectroscopic factors and asymptotic normalization coefficients for one-nucleon transfer reactions.

Talk

Important quantities that input to one-nucleon transfer reactions are one-nucleon overlap functions. Usually, they are modelled by single-particle wave functions that are solutions of one homogeneous Schrodinger equation with some "standard" Wood-Saxon potential. However, they must come from solution of a Schrodinger-like inhomogeneous equation with the source term that contains information...
