Thermal and atomic effects on coupled-channels heavy-ion fusion

Stellar nuclear fusion reactions take place in a hot, dense plasma within stars. To account for the effect of these environments, theory open quantum systems is used to conduct pioneering studies thermal and atomic effects on probability at broad range temperatures densities. Since low-lying excited states are more likely be populated stellar increase interaction rates, 188Os nucleus was as target that interacts with an inert 16O projectile. Key results showed yield average 15.5% 36.9% our test nuclei 0.1 0.5 MeV respectively, compared calculations zero temperature. Thermal could tested laboratory using targets prepared envisaged facilities exploiting laser-nucleus interactions.
