The aim of this paper is to apply a contextual probabilistic model (in the
spirit of Mackey, Gudder, Ballentine) to represent and to generalize some
results of quantum logic about possible macroscopic quantum-like (QL)
behaviour. The crucial point i... | arxiv topic:quant-ph |
arxiv_dataset-80705.3998 | Geometry of Borromean Halo Nuclei
nucl-th
We discuss the geometry of the highly quantal nuclear three-body systems
composed of a core plus two loosely bound particles. These Borromean nuclei
have no single bound two-body subsystem. Correlation plays a prominent role.
From consideration of the $B(E1)$ value extrac... | arxiv topic:nucl-th |
