Energy dependence of optical potential in the near barrier elastic scattering of 11B from 232Th

EPJ Web of Conferences, 2015
The elastic scattering cross sections of 11B projectile on the 232Th target have been measured at different bombarding energies close to the Coulomb barrier.

Incorporating Uncertainties in Atomic Data Into the Analysis of Solar and Stellar Observations: A Case Study in Fe XIII

, 2018
Information about the physical properties of astrophysical objects cannot be measured directly but is inferred by interpreting spectroscopic observations in the context of atomic physics calculations. Ratios of emission lines, for example, can be used to

Theory and applications of atomic and ionic polarizabilities [PDF]

, 2010
Atomic polarization phenomena impinge upon a number of areas and processes in physics. The dielectric constant and refractive index of any gas are examples of macroscopic properties that are largely determined by the dipole polarizability.

Frequency ratio of the 229mTh nuclear isomeric transition and the 87Sr atomic clock. [PDF]

Nature
Optical atomic clocks1,2 use electronic energy levels to precisely keep track of time. A clock based on nuclear energy levels promises a next-generation platform for precision metrology and fundamental physics studies.

Meson and Quark Degrees of Freedom and the Radius of the Deuteron [PDF]

, 1996
The existing experimental data for the deuteron charge radius are discussed. The data of elastic electron scattering are inconsistent with the value obtained in a recent atomic physics experiment.

Nuclear effects in atomic transitions

, 2010
Atomic electrons are sensitive to the properties of the nucleus they are bound to, such as nuclear mass, charge distribution, spin, magnetization distribution, or even excited level scheme.

Entanglement of orbital angular momentum states between an ensemble of cold atoms and a photon [PDF]

, 2006
Recently, atomic ensemble and single photons were successfully entangled by using collective enhancement [D. N. Matsukevich, \textit{et al.}, Phys. Rev. Lett. \textbf{95}, 040405(2005).], where atomic internal states and photonic polarization states were

Weak Interactions in Atoms and Nuclei: The Standard Model and Beyond

, 2003
Studies in nuclear and atomic physics have played an important role in developing our understanding of the Standard Model of electroweak interactions. We review the basic ingredients of the Standard Model, and discuss some key nuclear and atomic physics ...

Physics of our Days: Cooling and thermometry of atomic Fermi gases [PDF]

, 2016
We review the status of cooling techniques aimed at achieving the deepest quantum degeneracy for atomic Fermi gases. We first discuss some physics motivations, providing a quantitative assessment of the need for deep quantum degeneracy in relevant ...
