alpha-nucleus potentials and photon-induced nucleosynthesis
Galaviz, D.; Babilon, M.; Fulop, Zs.; Gyurky, Gy.; Hillier, R.; Mate, Z.; Mohr, P.; Rauscher, T.; Somorjai, E.; Zilges, A.; Zolnai, L. (2003-05-05)New data for the Sn-112,Sn-12 4(alpha,alpha) (112,124) Sn reaction have been measured and are presently analyzed. Results of the Sn-112 circle times alpha potential at the energy Ec.m approximate to 14 MeV are presented. ... -
Determination of a-nucleus potentials by alpha-elastic scattering and its implications for the gamma-process
Galaviz, D.; Babilon, M.; Fulop, Zs.; Gyurky, Gy.; Mate, Z.; Hillier, R.; Mohr, P.; Rauscher, T.; Somorjai, E.; Zilges, A.; Zolnai, L. (2003-05-19)Complete angular distributions for the reactions Sn-112,Sn-124(alpha,alpha)(112,124) Sn have been measured at different energies around the Coulomb barrier. Preliminary results for the Sn-112 circle times alpha and Sn-124 ... -
Experimental simulation of a stellar photon bath by bremsstrahlung: the astrophysical gamma-process
Mohr, P.; Vogt, K.; Babilon, M.; Enders, J.; Hartmann, T.; Hutter, C.; Rauscher, T.; Volz, S.; Zilges, A. (2000-08-31)The nucleosynthesis of heavy proton-rich nuclei in a stellar photon bath at temperatures of the astrophysical gamma-process was investigated where the photon bath was simulated by the superposition of bremsstrahlung spectra ... -
Measurement of the (gamma, n) cross section of the nucleus Au-197 close above the reaction threshold
Vogt, K.; Mohr, P.; Babilon, M.; Bayer, W.; Galaviz, D.; Hartmann, T.; Hutter, C.; Rauscher, T.; Sonnabend, K.; Volz, S.; Zilges, A. (2002-08-26)The cross section and the astrophysical reaction rate of the reaction Au-197(gamma,n)Au-196 have been measured close above the reaction threshold at E-thr = 8.071 MeV using the method of photoactivation. The results are ... -
Measurement of the (gamma,n) reaction rates of the nuclides Pt-190, Pt-192, and Pt-198 in the astrophysical gamma process
Vogt, K.; Mohr, P.; Babilon, M.; Enders, J.; Hartmann, T.; Hutter, C.; Rauscher, T.; Volz, S.; Zilges, A. (2001-05)The nucleosynthesis of heavy neutron-deficient nuclei in a stellar photon bath at the temperatures relevant for the astrophysical gamma process was investigated. In order to derive (gamma ,n) cross sections and reaction ...
