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 tar...

We analyse the origin of unexpected deep sub-barrier heavy-ion fusion hindrance in 64Ni+100Mo and 28Si+64Ni recations. Our analysis is based on improved coupled-channels approach, implemented by means finite element method. With aid Woods-Saxon potential experimental cross sections S-factors these reactions are remarkably well reproduced. found that account non-diagonal matrix elements coupling...
