The present paper examines the effect of temperature-dependent repulsive core potential on the fusion reactions of the $$\alpha $$ particle relevant to the production of p-nuclei such as $$^{154}$$ Sm, $$^{162}$$ Dy, $$^{166}$$ Er, and $$^{197}$$ Au. For this purpose, the $$\alpha $$ -nucleus potentials making use of the double folding model with the density-dependent CDM3Y3 interaction plus the temperature-dependent repulsion (CDM3Y3+Repulsion) are employed. In addition, three nuclear…

Total and partial cross sections of the $^{112}$Sn($\alpha,\gamma$)$^{116}$Te reaction measured via in-beam $\gamma$-ray spectroscopy
An extended database of experimental data is needed to address uncertainties of the nuclear-physics input parameters for Hauser-Feshbach calculations. Especially $\alpha$+nucleus optical model
Microscopic sub-barrier fusion calculations for the neutron star crust
Fusion of very neutron-rich nuclei may be important to determine the composition and heating of the crust of accreting neutron stars. Fusion cross sections are calculated using time-dependent
α -induced reactions on 115 In: Cross section measurements and statistical model analysis
Background: $\ensuremath{\alpha}$-nucleus optical potentials are basic ingredients of statistical model calculations used in nucleosynthesis simulations. While the nucleon+nucleus optical potential
High precision $^{89}$Y($\alpha$,$\alpha$)$^{89}$Y scattering at low energies
Elastic scattering cross sections of the $^{89}$Y($\alpha$,$\alpha$)$^{89}$Y reaction have been measured at energies E$_{c.m.}$ = 15.51 and 18.63 MeV. The high precision data for the semi-magic $N =
Role of exact treatment of thermal pairing in radiative strength functions of Dy161–163 nuclei
The enhancement of radiative strength function (RSF) in the region of low $\gamma$-rays energy ($E_{\gamma}\leq 12$ MeV), which is caused by the pygmy dipole resonance (PDR), is treated within the
Signature of shallow potentials in deep sub-barrier fusion reactions
We extend a recent study that explained the steep falloff in the fusion cross section at energies far below the Coulomb barrier for the symmetric dinuclear system $^{64}\mathrm{Ni}+^{64}\mathrm{Ni}$
Astrophysical S factor for α-capture on Sn112 in the p-process energy range
The cross section of the reaction $^{112}\mathrm{Sn}$($\ensuremath{\alpha},\ensuremath{\gamma})^{116}\mathrm{Te}$ has been measured in the energy range of astrophysical interest for the $p$-process.
Photo-induced nucleosynthesis: Current problems and experimental approaches
Abstract.Photon-induced reactions play a key role in the nucleosynthesis of rare neutron-deficient p -nuclei. The paper focuses on $\ensuremath{(\gamma,\alpha)}$ , $\ensuremath{(\gamma,{\rm p})}$ ,
Ni 64 + Sn 132 fusion within the density-constrained time-dependent Hartree-Fock formalism
We study fusion reactions of the $^{64}\mathrm{Ni}+^{132}\mathrm{Sn}$ system using the recently introduced density constrained time-dependent Hartree-Fock formalism. In this formalism the fusion
Measurement of the 187 Re(α ,n ) 190 Ir reaction cross section at sub-Coulomb energies using the Cologne Clover Counting Setup
Uncertainties in adopted models of particle+nucleus optical-model potentials directly influence the accuracy in the theoretical predictions of reaction rates as they are needed for reaction-network
