Abstract: Nuclear reactions feed the stars throughout their lives while producing all the chemical ele ments that surround us\, including those that are indispensable for life i tself to occur\, such as carbon or oxygen. The measurement of these reacti ons in the laboratory will be presented\, in a combination of nuclear phys ics and astrophysics. Here\, fusion reactions will be described as the dom inant mechanism in the collisions of heavy-ions at nuclear physics energie s. At very low energies\, fusion occurs via tunneling through the Coulomb barrier and is strongly sensitive to structure effects of the colliding nu clei\, like the formation of nuclear molecules and the associated symmetri es. In this low energy regime\, nuclear fusion is strongly connected with astrophysics. Indeed\, fusion in astrophysical environments often occurs a t temperatures which correspond to energies lower than what can be studied in the laboratory\, except for a few reactions. Among these reactions\, t he study of the carbon+carbon fusion probability at thermonuclear energies will be taken as an example\, as one of the most challenging nuclear phys ics reactions to be measured.
