Structure of p-shell hypernuclei [PDF]

open access: yesStrangeness Nuclear Physics, 2010
Shell-model calculations that include both Lambda and Sigma configurations with p-shell cores are used to interpret gamma-ray transitions in Lambda-7Li, -9Be, -10B, -11B, -12C, -15N, and -16O observed with the Hyperball array of Ge detectors. It is shown

Shell Structure of Exotic Nuclei [PDF]

open access: yesProgress in Particle and Nuclear Physics, 2006
Theoretical predictions and experimental discoveries for neutron-rich, short-lived nuclei far from stability indicate that the familiar concept of nucleonic shell structure should be considered as less robust than previously thought. The notion of single-

Rib‐reinforced Shell Structure [PDF]

open access: yesComputer Graphics Forum, 2017
AbstractShell structures are extensively used in engineering due to their efficient load‐carrying capacity relative to material volume. However, large‐span shells require additional supporting structures to strengthen fragile regions. The problem of designing optimal stiffeners is therefore becoming a major challenge for shell applications.

Nuclear level density in the statistical semiclassical micro-macroscopic approach [PDF]

open access: yesЯдерна фізика та енергетика, 2023
Level density ρ is derived for a finite system with strongly interacting nucleons at a given energy E, neutron N, and proton Z particle numbers, projection of the angular momentum M, and other integrals of motion, within the semiclassical periodic-orbit ...

Buckling Analysis for Wind Turbine Tower Design: Thrust Load versus Compression Load Based on Energy Method

open access: yesEnergies, 2020
Tubular steel towers are the most common design solution for supporting medium-to-high-rise wind turbines. Notwithstanding, historical failure incidence records reveal buckling modes as a common type of failure of shell structures.

Periodic-Orbit Bifurcation and Shell Structure in Reflection-Asymmetric Deformed Cavity [PDF]

open access: yes, 1997
Shell structure of the single-particle spectrum for reflection-asymmetric deformed cavity is investigated. Remarkable shell structure emerges for certain combinations of quadrupole and octupole deformations.
