    • Constraining the astrophysical origin of the p-nuclei through nuclear physics and meteoritic data 

      Rauscher, T.; Dauphas, N.; Dillmann, I.; Fröhlich, C.; Fülöp, Z.; Gyürky, G. (2013-06-01)
      A small number of naturally occurring, proton-rich nuclides (the p-nuclei) cannot be made in the s- and r-processes. Their origin is not well understood. Massive stars can produce p-nuclei through photodisintegration of ...

    • Mass measurements of neutron-deficient Y, Zr, and Nb isotopes and their impact on rp and νp nucleosynthesis processes 

      Xing, Y. M.; Li, K. A.; Zhang, Y. H.; Zhou, X. H.; Wang, M.; Litvinov, Yu A.; Blaum, K.; Wanajo, S.; Kubono, S.; Martínez-Pinedo, G.; Sieverding, A.; Chen, R. J.; Shuai, P.; Fu, C. Y.; Yan, X. L.; Huang, W. J.; Xu, X.; Tang, X. D.; Xu, H. S.; Bao, T.; Chen, X. C.; Gao, B. S.; He, J. J.; Lam, Y. H.; Li, H. F.; Liu, J. H.; Ma, X. W.; Mao, R. S.; Si, M.; Sun, M. Z.; Tu, X. L.; Wang, Q.; Yang, J. C.; Yuan, Y. J.; Zeng, Q.; Zhang, P.; Zhou, X.; Zhan, W. L.; Litvinov, S.; Audi, G.; Uesaka, T.; Yamaguchi, Y.; Yamaguchi, T.; Ozawa, A.; Fröhlich, C.; Rauscher, T.; Thielemann, F. K.; Sun, B. H.; Sun, Y.; Dai, A. C.; Xu, F. R. (2018-06-10)
      Using isochronous mass spectrometry at the experimental storage ring CSRe in Lanzhou, the masses of 82Zr and 84Nb were measured for the first time with an uncertainty of ∼10 keV, and the masses of 79Y, 81Zr, and 83Nb were ...

    • The Nuclear Reaction Network WinNet 

      Reichert, M.; Winteler, C.; Korobkin, O.; Arcones, A.; Bliss, J.; Eichler, M.; Frischknecht, U.; Fröhlich, C.; Hirschi, R.; Jacobi, M.; Kuske, J.; Martínez-Pinedo, G.; Martin, D.; Mocelj, D.; Rauscher, T.; Thielemann, F.-K. (2023-10-11)
      We present the state-of-the-art single-zone nuclear reaction network WinNet, which is capable of calculating the nucleosynthetic yields of a large variety of astrophysical environments and conditions. This ranges from the ...

    • Systematic study of (p,γ) reactions on Ni isotopes 

      Simon, A.; Spyrou, A.; Quinn, S.J.; Lin, L.-Y.; Stefanek, B.; Rauscher, T.; Fröhlich, C.; Battaglia, A.; Best, A.; Bucher, B.; Couder, M.; Fang, X.; Görres, J.; Kontos, A.; Li, Q.; Long, A.; Lyons, S.; Roberts, A.; Robertson, D.; Smith, K.; Smith, M.K.; Stech, E.; Tan, W.P.; Tang, X.D.; Wiescher, M.; Deyoung, P.A. (2013-05-09)
      A systematic study of the radiative proton capture reaction for all stable nickel isotopes is presented. The results were obtained using 2.0-6.0 MeV protons from the 11-MV tandem Van de Graaff accelerator at the University ...

    • Uncertainties in νp-process nucleosynthesis from Monte Carlo variation of reaction rates 

      Nishimura, N.; Rauscher, T.; Hirschi, R.; Cescutti, G.; Murphy, A. St J.; Fröhlich, C. (2019-10)
      It has been suggested that a νp-process can occur when hot, dense, and proton-rich matter is expanding within a strong flux of antineutrinos. In such an environment, proton-rich nuclides can be produced in sequences of ...
