35. Isomers in nuclear astrophysics

Sergio Almaraz-Calderon (Florida State University)

6/10/24, 11:40 AM

Nuclear isomers are metastable states with long half lives compared to typical nuclear excited states. Given that the nuclear properties of isomers are usually very different from those of the ground state, isomers that remain metastable in astrophysical environments can play an important role in nuclear astrophysics. Nuclear reactions on isomers affect the energy release, nucleosynthesis...

38. Continuum energy representation to study structure and reaction properties of loosely bound nuclei

IANNA

The study of the properties of loosely bound or unbound nuclei required the explicit consideration of the continuum spectrum of energy since the Fermi level is close to or even in the continuum. The continuum's single particle level density, with the Fermi gas subtracted, encodes information about its resonant structure. The Berggren representation explicitly isolates the resonant contribution...

30. How can inclusive Coulomb break-up measurements help in determining astrophysical radiative capture reaction rates?

MANUELA Rodríguez-Gallardo (Universidad de Sevilla)

6/10/24, 12:40 PM

A direct link between the Coulomb inclusive break-up probability and the radiative capture reaction rate for weakly bound systems can be established [1]. This link provides an indirect method to estimate reaction rates of astrophysical interest. This procedure can also assess the validity of different theoretical approaches that have been used to calculate reaction rates. In particular, this...

27. Extending radiative transfer simulations in kilonovae towards non-equilibrium regimes

Ricardo Ferreira da Silva (Laboratório de Instrumentação e Física Experimental de Partículas (LIP) and Faculdade de Ciências, Universidade de Lisboa (FCUL))

6/10/24, 1:10 PM

The recent observations of several neutron-star merger events and associated electromagnetic transients, particularly AT2017gfo observation, provided robust indications that heavy r-process elements such as lanthanides and eventually actinides can be synthesised in these explosive environments [1]. Nonetheless, pinpointing particular features in the spectra, and linking them to the absorption...
