Nuclear uncertainties associated with the ejecta of a neutron-star black-hole accretion disk

Autor: Mumpower, M. R., Sprouse, T. M., Miller, J. M., Lund, K. A., Garcia, J. Cabrera, Vassh, N., McLaughlin, G. C., Surman, R.

The simulation of heavy element nucleosynthesis requires input from yet-to-be-measured nuclear properties. The uncertainty in the values of these off-stability nuclear properties propagates to uncertainties in the predictions of elemental and isotopi

Employing FREYA for fission product yield evaluations

Autor: Vogt R., Randrup J., Vassh N., Sprouse T., Surman R.

Publikováno v: EPJ Web of Conferences, Vol 242, p 03002 (2020)

The fast event-by-event fission code FREYA (Fission Reaction Event Yield Algorithm) generates large samples of complete fission events while employing only a few physics-based parameters. Not only is FREYA fast, it is also flexible, able to employ a

The impact of global nuclear mass model uncertainties on r-process abundance predictions

Autor: Mumpower M., Surman R., Aprahamian A.

Publikováno v: EPJ Web of Conferences, Vol 93, p 03003 (2015)

Rapid neutron capture or ‘r-process’ nucleosynthesis may be responsible for half the production of heavy elements above iron on the periodic table. Masses are one of the most important nuclear physics ingredients that go into calculations of r-pr
