Description
The HISPEC/DESPEC collaboration is a part of NUSTAR (NUclear STructure, Astrophysics and
Reactions), which constitutes one of the four scientific pillars of the international FAIR facility
currently under construction in Darmstadt, Germany. Experiments are divided into two main
areas: high-resolution in-flight spectroscopy (HISPEC) and stopped-beam experiments
(DESPEC).
In the future, both HISPEC and DESPEC experiments will be provided exotic secondary beams
by the new Super-conducting FRagment Separator (Super-FRS), where the SIS-18 and SIS-100
synchrotrons will deliver high-energy beams to the Super-FRS production target. The DESPEC
setup was successfully commissioned in 2020 in the so-called ‘FAIR Phase-0’ using exotic
beams delivered by the SIS-18 and FRagment Separator (FRS) facilities of the existing GSI
campus, with several campaigns running in 2021-2024.
In this talk I will show scientific highlights from the DESPEC Phase-0 campaigns, including
investigations close to doubly-magic 100Sn and in the heavy neutron-rich regions crossing the
N=126 shell gap. Preliminary results from the worlds first in-flight fragmentation of 170Er ions,
providing a wealth of information in the highly-deformed rare-earth nuclei with A~160-170,
will also be presented. In addition, the medium- and long-term perspectives for DESPEC
experiments at the Super-FRS in the coming years will be discussed.
