<b><i>Ab Initio</i> Calculations of Light-Ion Fusion Reactions</b>
<div>
<p> The fundamental description of both structural properties and
reactions of light nuclei in terms of<br>
constituent protons and neutrons interacting through
nucleon-nucleon and three-nucleon forces is <br>
a long-sought goal of nuclear theory. I will briefly present a
promising technique, built upon the <i><br>
ab initio</i> no-core shell model, which emerged recently as a
candidate to reach such a goal: the<br>
no-core shell model/resonating-group method (NCSM/RGM). This
approach, capable of describing<br>
simultaneously both bound and scattering states in light nuclei,
complements a microscopic cluster <br>
technique with the use of two-nucleon realistic interactions,
and a microscopic and consistent <br>
description of the nucleon clusters. I will discuss applications
to light nuclei binary scattering<br>
processes and fusion reactions that power stars and Earth based
fusion facilities, such as the <br>
deuterium-3He fusion, and outline the progress toward the
inclusion of the three-nucleon force<br>
into the formalism and the treatment of three-body clusters. </p>
