We present explicit calculations of channel-specific dielectronic recombination cross sections for hydrogen-like germanium, Ge(XXXII); selenium, Se(XXXIV); and krypton, Kr(XXXVI). The convoluted cross sections characterize K-shell emission spectra over a wide energy range where contributions from high-n (n = 2–10), satellite lines are included. The high-n contributions presented are important for better diagnostics in the domain of high-temperature plasmas. PACS Nos.: 32.30.Rj, 32.70.Rm, 34.70.te

Abstract The phenomenological strengths of the real part of the optical potential, obtained from elastic scattering data analyses within the optical model approach, present significant energy-dependence. This behavior has been associated to the intrinsic energy-dependence of the effective nucleon-nucleon interaction. However, in earlier works, we proposed that at least part of this dependence can arise from the effect of couplings to inelastic states of the nuclei. In order to deepen this study, in this paper we present extensive data analyses for the elastic scattering and inelastic excitation of 111 states of 208Pb, for the 4He + 208Pb system in a wide energy range. With the purpose of comparison, the theoretical cross sections are obtained in different approaches for the imaginary part of the potential, and within both contexts: optical model (distorted wave Born approximation) and coupled-channel calculations.

First Time

The average cross-sections were measured at the first time for 7Bе population at bremsstrahlung end-point energies 40 and 55 MeV and for the 10B(γ,t)7Bе reaction at bremsstrahlung end-point energy 20 MeV. The theoretical calculations carried out within the framework of the software packages EMPIRE-3.2 and TALYS-1.9 demonstrate the domination of the nonstatistical processes.
