TL;DR: The unbound nuclei He-9 and He-10 have been produced in proton-knockout reactions from a 280 MeV/u Li-11 beam impinging on a liquid hydrogen target at the ALADIN-LAND setup at GSI as discussed by the authors.

TL;DR: In this article, the gluon polarisation in the nucleon has been determined by detecting charm production via D 0 meson decay to charged K and π in polarised muon scattering off a longitudinally polarised deuteron target.
Journal ArticleDOI
First experimental observation of superscars in a pseudointegrable barrier billiard.
Eugene Bogomolny,Barbara Dietz,Thomas Friedrich,M. Miski-Oglu,Achim Richter,F. Schäfer,C. Schmit +6 more
TL;DR: Recently predicted superscars have been identified experimentally and--using the well-known analogy between the electric field strength and the quantum mechanical wave function in a two-dimensional microwave billiard--their properties determined.
Journal ArticleDOI
Decay of classical chaotic systems: The case of the Bunimovich stadium.
TL;DR: The escape of an ensemble of particles from the Bunimovich stadium via a small hole has been studied numerically and the decay probability starts out exponentially but has an algebraic tail.
