    • Activation method combined with characteristic X-ray counting : A possibility to measure (alpha, gamma) cross sections on heavy p-nuclei 

      Kiss, G. G.; Szuecs, T.; Gyuerky, Gy.; Fueloep, Zs.; Farkas, J.; Kertesz, Zs.; Somorjai, E.; Laubenstein, M.; Froehlich, C.; Rauscher, T. (2011-10-01)
      For an improved modeling of the astrophysical nucleosynthesis of p-nuclei, low energy cross section data of alpha-induced reactions on heavy isotopes are needed. Technical difficulties hamper the experimental determination ...
    • Determining reaction cross sections via characteristic X-ray detection : alpha-induced reactions on Tm-169 for the astrophysical gamma-process 

      Kiss, G. G.; Rauscher, T.; Szuecs, T.; Kertesz, Zs.; Fueloep, Zs.; Gyuerky, Gy.; Froehlich, C.; Farkas, J.; Elekes, Z.; Somorjai, E. (2011-01-17)
      The cross sections of the Tm-169(alpha, gamma)Lu-173 and Tm-169(alpha,n)Lu-172 reactions have been measured first time using a new method, by detecting the characteristic X-ray radiation following the electron capture-decay ...
    • Erratum: Iron-60 evidence for early injection and efficient mixing of stellar debris in the protosolar nebula (vol 686, pg 560, 2008) 

      Dauphas, N.; Cook, D. L.; Sacarabany, A.; Froehlich, C.; Davis, A. M.; Wadhwa, M.; Pourmand, A.; Rauscher, T.; Gallino, R. (2009-02-01)

      Dauphas, N.; Cook, D. L.; Sacarabany, A.; Froehlich, C.; Davis, A. M.; Wadhwa, M.; Pourmand, A.; Rauscher, T.; Gallino, R. (2008-07)
    • Mass measurements in the vicinity of the r p-process and the nu p-process paths with the Penning trap facilities JYFLTRAP and SHIPTRAP 

      Weber, C.; Elomaa, V. -V.; Ferrer, R.; Froehlich, C.; Ackermann, D.; Aystoe, J.; Audi, G.; Batist, L.; Blaum, K.; Block, M.; Chaudhuri, A.; Dworschak, M.; Eliseev, S.; Eronen, T.; Hager, U.; Hakala, J.; Herfurth, F.; Hessberger, F. P.; Hofmann, S.; Jokinen, A.; Kankainen, A.; Kluge, H. -J.; Langanke, K.; Martin, A.; Martinez-Pinedo, G.; Mazzocco, M.; Moore, I. D.; Neumayr, J. B.; Novikov, Yu. N.; Penttilae, H.; Plass, W.

M.; Sonoda, T.; Thielemann, F. -K.; Thirolf, P. G.; Vorobjev, G. K. (2008-11)
      The masses of very neutron-deficient nuclides close to the astrophysical r p- and nu p-process paths have been determined with the Penning trap facilities JYFLTRAP at JYFL/Jyvaskyla and SHIPTRAP at GSI/Darmstadt. Isotopes ...
    • Proton-rich nucleosynthesis and nuclear physics 

      Rauscher, T.; Froehlich, C. (American Institute of Physics (AIP), 2012)
      Although the detailed conditions for explosive nucleosynthesis are derived from astrophysical modeling, nuclear physics determines fundamental patterns in abundance yields, not only for equilibrium processes. Focussing on ...
    • 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), ...
    • Reaction Rate Uncertainties and the nu p-Process 

      Froehlich, C.; Rauscher, T. (American Institute of Physics (AIP), 2012)
      Current hydrodynamical simulations of core collapse supernovae find proton-rich early ejecta. At the same time, the models fail to eject neutron-rich matter, thus leaving the origin of the main r-process elements unsolved. ...
    • Resonance analysis of (147)Sm(n,alpha) cross sections : Comparison to optical model calculations and indications of nonstatistical effects 

      Koehler, P. E.; Gledenov, Y.M.; Rauscher, T.; Froehlich, C. (2004-01)
      We have measured the (147)Sm(n,alpha) cross section from 3 eV to 500 keV and performed an R-matrix analysis in the resolved region (E(n)
    • What are the astrophysical sites for the r-process and the production of heavy elements?
