Intermediate Energy NN Phase Shifts. II

Inequalities between fixed energy phase shifts II

In this note we continue the study of the properties of phase shifts arising in the 3D inverse scattering with spherically symmetric potential. We provide various inequalities between the first two phase shift for some potential classes.

From Skyrmions to NN phase shifts.

We study the NN phaseshifts in a Hamiltonian obtained from quantization of the collective modes in the Skyrme model. We show that a combination of an adiabatic and diabatic approximation gives a good NN force, with sufficient attraction to produce a bound deuteron. The description of the repulsive core appears to be the main cause for the remaining discrepancies between the Skyrme model force a...

Generating Phase Shifts from Pseudo State Energy Shifts

Neural encoding of binocular disparity: Energy models, position shifts and phase shifts

Neurophysiological data support two models for the disparity selectivity of binocular simple and complex cells in primary visual cortex. These involve binocular combinations of monocular receptive fields that are shifted in retinal position (the position-shift model) or in phase (the phase-shift model) between the two eyes. This article presents a formal description and analysis of a binocular ...

First Order Phase Transition in Intermediate Energy Heavy Ion Collisions

We model the disassembly of an excited nuclear system formed as a result of a heavy ion collision. We find that, as the beam energy in central collisions in varied, the dissociating system crosses a liquid-gas coexistence curve, resulting in a first-order phase transition. Accessible experimental signatures are identified: a peak in specific heat, a power-law yield for composites, and a maximum...
