    Determination of the Neutron-Capture Rate of 17C for the R-process Nucleosynthesis 
    Heine, M.; Typel, S.; Wu, M.-R.; Adachi, T.; Aksyutina, Y.; Alcantara, J.; Altstadt, S.; Alvarez-Pol, H.; Ashwood, N.; Atar, L.; Aumann, T.; Avdeichikov, V.; Barr, M.; Beceiro-Novo, S.; Bemmerer, D.; Benlliure, J.; Bertulani, C. A.; Boretzky, K.; Borge, M. J. G.; Burgunder, G.; Caamano, M.; Caesar, C.; Casarejos, E.; Catford, W.; Cederkall, J.; Chakraborty, S.; Chartier, M.; Chulkov, L. V.; Cortina-Gil, D.; Crespo, R.; Datta Pramanik, U.; Dıaz Fernandez, P.; Dillmann, I.; Elekes, Z.; Enders, J.; Ershova, O.; Estrade, A.; Kanungo, R. (American Physical Society, 2017-01-30)
    With the R3B-LAND setup at GSI we have measured exclusive relative-energy spectra of the Coulomb dissociation of 18C at a projectile energy around 425A MeV on a lead target, which are needed to determine ...

    Modelling self-pollution of globular clusters from asymptotic giant branch stars 
    Fenner, Y.; Campbell, S.; Karakas, A. I.; Lattanzio, J. C.; Gibson, Brad K. (Royal Astronomical SocietyOxford University Press, 2004)
    A self-consistent model of the chemical evolution of the globular cluster NGC 6752 is presented to test a popular theory that observed abundance anomalies are due to ‘internal pollution’ from intermediate-mass asymptotic ...

    Reaction rate uncertainties and the production of [superscript 19]F in asymptotic giant branch stars 
    Lugaro, Maria; Ugalde, Claudio; Karakas, A. I.; Gorres, Joachim; Wiescher, Michael; Lattanzio, John C.; Cannon, Robert C. (American Astronomical SocietyIOP Publishing, 2004-11-10)
    We present nucleosynthesis calculations and the resulting [superscript 19]F stellar yields for a large set of models with different masses and metallicity. During the asymptotic giant branch (AGB) phase, [superscript 19]F ...

    The uncertainties in the [superscript 22]Ne+[alpha]-capture reaction rates and the production of the heavy magnesium isotopes in asymptotic giant branch stars of intermediate mass 
    Karakas, A. I.; Lugaro, M. A.; Wiescher, M.; Gorres, J.; Ugalde, C. (American Astronomical Society, 2006-05-20)
    We present new rates for the [superscript 22]Ne([alpha], n)[superscript 25]Mg and [superscript 22]Ne([alpha], [gamma])[superscript 26]Mg reactions, with uncertainties that have been considerably reduced compared to previous ...
