    • Alpha-induced reactions for the astrophysical p-process : the case of (151)Eu 

      Gyuerky, G. Y.; Elekes, Z.; Farkas, J.; Fueloep, Z. S.; Kiss, G. G.; Somorjai, E.; Szuecs, T.; Guray, R. T.; Ozkan, N.; Yalcin, C.; Rauscher, T. (IOP Publishing Ltd., 2010)
      The cross sections of (151)Eu(alpha, gamma)(155)Tb and (151)Eu(alpha,n)(154)Tb reactions have been measured with the activation method. Some aspects of the measurement are presented here to illustrate the requirements of ...

    • Comparison of experimental and calculated S-factors of the p-process reaction Sm-144(alpha,gamma)Gd-148 

      Somorjai, E.; Fulop, Zs.; Kiss, A.Z.; Rolfs, C.E.; Trautvetter, H.P.; Greife, U.; Junker, M.; Goriely, S.; Arnould, M.; Rayet, M.; Rauscher, T.; Oberhummer, H. (IOP Publishing Ltd., 1998)
      The cross section of the Sm-144(alpha,gamma)Gd-148 reaction has been measured at bombarding energies in the 10.5 - 13.4 MeV range using an activation method based on the off-line alpha-activity measurement of the Gd-148 ...

    • Differences between stellar and laboratory reaction cross sections 

      Rauscher, T. (IOP Publishing Ltd., 2010)
      Nuclear reactions proceed differently in stellar plasmas than in the laboratory due to the thermal effects in the plasma. On one hand, a target nucleus is bombarded by projectiles distributed in energy with a distribution ...

    • Experimental cross section of Sm-144(alpha, gamma)Gd-148 and implications for the p-process 

      Somorjai, E.; Fulop, Zs.; Kiss, A.Z.; Rolfs, C.E.; Trautvetter, H.P.; Greife, U.; Junker, M.; Goriely, S.; Arnould, M.; Rayet, M.; Rauscher, T.; Oberhummer, H. (1998-05-20)
      The cross section of the Sm-144(alpha, gamma) Gd-148 reaction has been measured at bombarding energies in the 10.5-13.4 MeV range using an activation method based on the off-line alpha-activity measurement of the Gd-148 ...

    • Network calculations for r-process nucleosynthesis 

      Petermann, I.; Martinez-Pinedo, G.; Arcones, A.; Hix, W. R.; Kelic, A.; Langanke, K.; Panov, I.; Rauscher, T.; Schmidt, K-H; Thielemann, Friedrich-Karl; Zinner, N. (IOP Publishing Ltd., 2010)
      The r-process is known to be responsible for the synthesis of about half of the elements heavier than iron, nevertheless its astrophysical site has not yet been clearly ascertained, but observations indicate that at least ...

    • The r-, p-, and nu p-Process 

      Thielemann, Friedrich-Karl; Dillmann, I.; Farouqi, K.; Fischer, T.; Froehlich, C.; Kelic-Heil, A.; Korneev, I.; Kratz, K.L.; Langanke, K.; Liebendoerfer, M.; Panov, I. V.; Martinez-Pinedo, G.; Rauscher, T. (IOP Publishing Ltd., 2010)
      The processes discussed in this review are three of the four nucleosynthesis processes involved in producing heavy nuclei beyond Fe (not counting the rp-process in Xray bursts). Opposite to the fourth process (the s-process), ...
