Session 9: Nuclear Structure, Reactions and Dynamics
- Alinka Lépine-Szily (USP)
The single-particle excitations, particle-hole interactions, and mixing of various single particle configurations in nuclei with few valence particles or holes around $^{132}$Sn have been the subject of contemporary interest, both experimentally [1–4] and theoretically [5]. The excited states of these neutron-rich nuclei provide key inputs to understand the effective interactions in terms of...
The medium-to-heavy mass ytterbium isotopes ($_{70}$Yb) in the rare-earth mass region are known to be well-deformed nuclei, which can be populated to very high spin. Spectroscopic information becomes scarcer as the neutron number increases, impeding the understanding of nuclear structure in this mass region, where interesting phenomena, such as shape coexistence, have been predicted. The lack...

Halo phenomenon has long been a hot topic in nuclear physics. Due to the weakly binding nature, the Fermi surface of a halo nucleus is very close to the continuum threshold, and the pairing interaction can scatter nucleons from bound states to resonant ones in the continuum. It is therefore necessary to take into account the pairing correlations and continuum effects in describing the halo...
I will presented a novel Monte Carlo technique based on DSAM (Doppler Shift Attenuation Method), which has been developed to determine lifetimes of excited states in the tens to-hundreds femtoseconds range in products of low-energy heavy-ion binary reactions [1]. These reaction processes are characterized by large energy dissipation, leading to complex velocity distributions which do not allow...
