Scattering of weakly bound nuclei with a pronounced cluster structure is strongly affected by their breakup. Usually, this mechanism is accounted for in a three-body model with pairwise potentials. The interaction potentials between complex systems a

Theoretical models of low-energy (d, p) single-neutron transfer reactions are a crucial link between experimentation, nuclear structure, and nuclear astrophysical studies. Whereas reaction models that use local optical potentials are insensitive to s

It is impossible to predict the life cycle of stars and how the chemical composition of the Universe evolved without detailed knowledge of the rates of nuclear reactions that take place in them. To provide astrophysicists with such knowlegde is a cha

We present an approach to halo transfer in (p ,d) and (d ,p) reactions in which excitation and breakup effects are treated in a simple way. The method assumes that halo excitation energies are small compared with kinetic energies in the channel conta

At very low energies of astrophysical interest, the $^{7}\mathrm{Be}$(p,\ensuremath{\gamma}${)}^{8}$B reaction is almost totally peripheral. Consequently, the overall normalization of the cross section for this reaction is defined by the asymptotic n

We point out a simple relation between the nuclear vertex constant (NVC) and the overall normalization of the astrophysical $S$ factor. Using predicted values of the NVC for the virtual decay of $^{8}\mathrm{B}\ensuremath{\rightarrow}^{7}\mathrm{Be}+
