    Approaching the precursor nuclei of the third r-process peak with RIBs 
    Domingo-Pardo, C.; Caballero-Folch, R.; Agramunt, J.; Algora, A.; Arcones, A.; Ameil, F.; Ayyad, Y.; Benlliure, J.; Bowry, M.; Calvino, F.; Estrade, Alfredo (IOP Publishing Limited, 2016)
    The rapid neutron nucleosynthesis process involves an enormous amount of very exotic neutron-rich nuclei, which represent a theoretical and experimental challenge. Two of the main decay properties that affect the final ...

    Knockout and fragmentation reactions using a broad range of tin isotopes 
    Rodríguez-Sánchez, J. L.; Benlliure, J.; Bertulani, C. A.; Vargas, J.; Ayyad, Y.; Alvarez-Pol, H.; Atkinson, J.; Aumann, T.; Beceiro-Novo, S.; Boretzky, K.; Caamaño, M.; Estrade, Alfredo (American Physical Society, 2017-09-05)
    Production cross sections of residual nuclei obtained by knockout and fragmentation reactions of different tin isotopes accelerated at 1A GeV have been measured with the fragment separator (FRS) at GSI, Darmstadt. The new ...

    Neutron skin and signature of the N = 14 shell gap found from measured proton radii of [superscript 17−22] N 
    Bagchi, Soumya; Kanungo, Rituparna; Horiuchi, W.; Hagen, G.; Morris, T.D.; Stroberg, S.R.; Suzuki, T.; Ameil, F.; Atkinson, Joel; Ayyad, Y.; Cortina-Gil, D.; Dillmann, I.; Estradé, Alfredo; Evdokimov, A.; Farinon, F.; Geissel, H.; Guastalla, G.; Janik, R.; Kaur, Satbir; Knöbel, R.; Kurcewicz, J.; Litvinov, Yu.A.; Marta, M.; Mostazo, M.; Mukha, I.; Nociforo, C.; Ong, H.J.; Pietri, S.; Prochazka, A.; Scheidenberger, C.; Sitar, B.; Strmen, P.; Takechi, M.; Tanaka, J.; Tanaka, Yoshiki K.; Tanihata, I.; Terashima, S.; Vargas, J.; Weick, H.; Winfield, J.S. (ElsevierNorth-Holland, 2019-01-21)
    A thick neutron skin emerges from the first determination of root mean square radii of the proton distributions for 17−22N from charge changing cross section measurements around 900A MeV at GSI. Neutron ...

    Observation of large enhancements of charge exchange cross sections with neutron-rich carbon isotopes 
    Tanihata, I.; Terashima, S.; Kanungo, Rituparna; Ameil, F.; Atkinson, J.; Ayyad, Y.; Cortina-Gil, D.; Dillmann, I.; Estrade, Alfredo; Evdokimov, A. (Oxford University Press, 2016-04)
    Production cross sections of nitrogen isotopes from high-energy (∼950 MeV per nucleon) carbon isotopes on hydrogen and carbon targets have been measured for the first time for a wide range of isotopes (A = 12 to 19). The ...

    Parameter-free calculation of charge-changing cross sections at high energy 
    Suzuki, Y.; Horiuchi, W.; Terashima, S.; Kanungo, Rituparna; Ameil, F.; Atkinson, J.; Ayyad, Y.; Cortina-Gil, D.; Dillmann, I.; Estrade, Alfredo (American Physical Society, 2016-07-05)
    Charge-changing cross sections at high energies are expected to provide useful information on nuclear charge radii. No reliable theory to calculate the cross section has yet been available.We develop a formula using Glauber ...

    Proton radius of [superscript 14]Be from measurement of charge-changing cross sections 
    Terashima, S.; Tanihata, I.; Kanungo, Rituparna; Estrade, Alfredo; Horiuchi, W.; Ameil, F.; Atkinson, J.; Ayyad, Y.; Cortina-Gil, D.; Dillmann, I. (Oxford University Press, 2014-10-06)
    The charge-changing cross sections of 7,9−12,14Be have been measured at 900A MeV on a carbon target. These cross sections are discussed both in terms of a geometrical and a Glauber model. From several ...

    Search for [eta prime](958)-nucleus bound states by (p, d) reaction at GSI and FAIR 
    Fujioka, H.; Ayyad, Y.; Benlliure, J.; Brinkmann, K.-T; Friedrich, S.; Geissel, H.; Gellanki, J.; Guo, C.; Gutz, E.; Kanungo, Rituparna (Jagiellonian University, 2015-01)
    The mass of the [eta prime] meson is theoretically expected to be reduced at finite density, which indicates the existence of [eta prime]–nucleus bound states. To investigate these states, we perform missing-mass spectroscopy ...
