Abstract:

We develop a Thomas Fermi theory to study the core polarization effects in Λ hypernuclei. Nuclei in the range of 10B to 243Am are included. Core polarization energies and changes in rms radii due to presence of Λ are calculated. It is shown that core polarization effects depend crucially on the effective compression modulus of the nucleus rather than on the compression modulus of the corresponding infinite nuclear matter.

Quadrupole Q moments and effective charges are calculated for 9C, 11C, 17C and 19C exotic nuclei using shell model calculations. Excitations out of major shell space are taken into account through a microscopic theory which are called core-polarization effects. The simple harmonic oscillator potential is used to generate the single particle matrix elements of 9,11,17,19C.

Abstract:

Oscillator strengths for the alkali group of elements have been computed through the quantum defect orbital (QDO) formalism. Three forms of the dipole transition moment have been employed, two of them accounting for core–valence polarization. Clear improvement is obtained over the nonpolarized calculations for the lighter elements, whereas for K, Rb, and Cs, the additional inclusion of spin–orbit effects is shown to be required.

The method of image charges is considered to take into account surface polarization, considering a metallic, an unpolarizable, and a dielectric nano-core. It is observed that, for all cases, a moderate shrinking–swelling effect appears with an increase in the electrostatic coupling parameter. This effect occurs under high Manning ratios.

Systematic trends of individual oscillator strengths along the isoelectronic sequence are also shown in a graphical form.

Abstract:

The study of NN interactions involves the calculation through inelastic electron scattering from longitudinal shape factors. The factors that come into play in the determination of the longitudinal shape factor for inelastic electron scattering are the transfer momentum and angular momentum. We delve into the analysis of electron scattering shape factors as well as CP — standing for nuclear polarization — in longitudinal inelastic shell models. This is done using NuShellX, where we employ a sum potential HO to look at 10 B, 39 K, and 19 F nuclei. Among the computations carried out include thos

Abstract:

A systematic study of the magnetic properties of deformed odd-neutron 137–145Ce isotopes using the microscopic quasiparticle phonon nuclear model (QPNM) has been presented. The QPNM includes residual spin–spin interaction in both isoscalar and isovector channels. The analysis shows that in the isoscalar channel contributions to the magnetic moment coming from the neutron and proton systems practically cancel out each other. On the other hand, in the isovector channel, the coherent contribution coming from the quasiparticle–phonon interactions leads to a spin polarization (core polarization), w

Abstract:

Predictable polarization is everywhere: we can often predict how people’s opinions, including our own, will shift over time. Extant theories either neglect the fact that we can predict our own polarization, or explain it through irrational mechanisms. They needn’t. Empirical studies suggest that polarization is predictable when evidence is ambiguous, that is, when the rational response is not obvious. I show how Bayesians should model such ambiguity and then prove that—assuming rational updates are those which obey the value of evidence—ambiguity is necessary and sufficient for the rationality

Abstract:

Context. Several strong resonance lines, such as H I Ly-α, Mg II k, Ca II K, and Ca I 4227 Å, are characterized by deep and broad absorption profiles in the solar intensity spectrum. These resonance lines show conspicuous linear scattering polarization signals when observed in quiet regions close to the solar limb. Such signals show a characteristic triplet-peak structure with a sharp peak in the line core and extended wing lobes. The line core peak is sensitive to the presence of magnetic fields through the Hanle effect, which however is known not to operate in the line wings. Recent theoreti
