TL;DR: The present results validate the Brink-Axel hypothesis for ^{96}Mo and provide independent confirmation of the methods used to separate gamma strength function and level density in γ decay experiments.

TL;DR: An interacting boson model sum rule for the strength of exciting the magnetic dipole scissors mode is used to relate this strength to the quadrupole deformation, resulting in a parameter-free description of the M1 transition strength over the entire range of nuclei from Nd to W studied experimentally.

TL;DR: Measurements on a superconducting three-dimensional, partly chaotic microwave billiard shaped such as a small deformed cup and a bouncing ball formula for electromagnetic billiards are presented and periodic orbits of the classical system are presented.

TL;DR: In this paper, the transverse and longitudinal momentum distributions of Li-9 fragments from Li-11 break-up reactions in C, Al and Pb targets have been measured at 280 MeV/u.

TL;DR: A thorough study of the fluctuation properties in the energy spectra of the unprecedented set of nuclear bound states using the method of Bayesian inference involving a quantitative measure, called the chaoticity parameter f, which also interpolates between Poisson statistics expected for regular systems and Gaussian orthogonal ensemble (GOE) predicted for chaotic systems.
