[Isac-journal-club] Journal/Snack Club Wednesday Oct 11 3:30 MOB Theory Room

[journalclub]

Hi everyone,

the next Journal Club is this Wednesday at 3:30 in the MOB Theory Room.
We'll be discussing "Observation of the Isovector Giant Monopole
Resonance via the 28Si(10Be,10B∗[1.74  MeV]) Reaction at 100  AMeV"
(https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.118.172501).

Hope to see you there,
Matthias

Questions:

1. What is the Isovector Giant Monopole Resonance?
2. How does it differ from the other excitation modes mentioned in the
paper?
3. How was the 28Si(10Be,10B∗[1.74  MeV]) reaction used as a filter to
select ΔS=0 events?
4. What was the advantage of using GRETINA for in this experiment?
5. How is the monopole contribution extracted?
6. What possible explanations for the disagreement between experimental
and theoretical cross sections are given?
