“…The effect is important in astrophysical scenarios, where almost all nuclear reactions happen at low energies and nuclei are not alone in the stellar plasma. The predicted effect was confirmed experimentally, but its measured magnitude was very often way above predictions [2][3][4][5][6][7][8][9][10][11]. Although the theory predicts an independence of electron screening on the nuclear surroundings, measurements of the same reactions in different environments gave different magnitudes of electron screening.…”

“…The upper panel of the figure shows a part of the γ-ray spectrum from the germanium detector. The three distinct peaks clearly seen are the full absorption (5626 keV), single escape (5626-511 keV) and double escape (5626-1022 keV) peaks resulting from the 2 H(p,γ) 3 He reaction. The full absorption energy of 5626 keV is the sum of the reaction Q value (5493 keV) and beam energy in the centerof-mass system, together with the Doppler correction.…”

Abstract. Electron screening enhances nuclear reaction cross sections at low energies. We studied the nuclear reaction 1 H( 19 F,αγ) 16 O in inverse kinematics in different solid hydrogen targets. Measured resonance strengths differed by up to a factor of 10 in different targets. We also studied the 2 H(p,γ) 3 He fusion reaction and observed electrons emitted as reaction products instead of γ rays. In this case electron screening greatly enhances internal conversion probability.

“…The absolute values of experimental screening energies are by a factor of two smaller than those calculated in the framework of the self-consistent dielectric function theory. Still, the host material dependence can be described rather well, indicating importance of the valence electron density in target materials [9]. Similar effects are also expected for alpha decays for which one should observe an environmental influence on the decay constants.…”

Recently, the electron screening effect in metallic environments has been experimentally investigated by many groups in low-energy nuclear reactions. The similar effect is expected in radioactive decays where the decay constant should be dependent on the valence electron density of the host material. Since metals represents a very good model for dense astrophysical plasmas, comparison of both effects can deliver new information about mechanism of the enhanced electron screening and consequences for nuclear processes taking place in stellar interior. Here, we present a new experimental investigation of screening effect in the d + d nuclear reactions under UHV conditions. Based on those experimental results a host material dependence of the alpha decay probability has been predicted. 10th Symposium on Nuclei in the Cosmos

Electron screening effect was studied on different hydrogen containing targets with the 7 Li, 11 B and 19 F ion beams. Results show large electron screening potentials strongly dependent on the proton number Z of the projectile. The largest ever measured screening potential with the value about a factor of 50 above the calculations from the model in adiabatic limit was observed in the graphite target containing hydrogen as an impurity.
