Abstract Isotopic yields of fragments emitted from projectile sources in peripheral collisions at Fermi and relativistic energy regimes are studied in the framework of the statistical multifragmentation model for an ensemble of excited both projectile and midrapidity sources. The data of FAZIA and FRS experiments and results of their theoretical analyses are compared together with each other to investigate

Many-body forces, and specially three-body forces, are sometimes a relevant ingredient in various fields, such as atomic, nuclear or hadronic physics. As their precise structure is generally difficult to uncover or to implement, phenomenological effective forces are often used in practice. A form commonly used for a many-body variable is the square-root of the sum of two-body variables. Even in this

$$\phi $$ Meson Photoproduction on the Nucleon and $${}^4$$ He Targets Few-Body Syst. (IF 1.6) Pub Date : 2024-03-10
Abstract We study the reaction mechanism of \(\phi \) -meson photoproduction on the nucleon and \({}^4\) He targets by using a dynamical model based on a Hamiltonian. In addition to the dominant contribution of the Pomeron exchange, various meson exchanges are considered in the t channel to describe the CLAS data in the low energy region \({\sqrt{s}} = (1.97 - 2.84)\) GeV. The direct \(\phi \) radiations

Breakup Amplitudes from the Pseudostate Extension of the Coupled-Reaction-Channels Method Few-Body Syst. (IF 1.6) Pub Date : 2024-03-02
Abstract A pseudochannel extension of the coupled-reaction-channel (CRC) ansatz had been used in earlier work to simulate the effect of the breakup channel on the rearrangement amplitudes. Comparisons with benchmark results on model systems established that rearrangement amplitudes and total breakup probability could be obtained accurately. However, achieving the same level of accuracy with respect

Classical ‘Spin’ Filtering with Two Degrees of Freedom and Dissipation Few-Body Syst. (IF 1.6) Pub Date : 2024-02-17
Abstract Coupling of orbital motion to a spin degree of freedom gives rise to various transport phenomena in quantum systems that are beyond the standard paradigms of classical physics. Here, we discuss features of spin-orbit dynamics that can be visualized using a classical model with two coupled angular degrees of freedom. Specifically, we demonstrate classical ‘spin’ filtering through our model

Characterizing Klein–Fock–Gordon–Majorana Particles in (1 + 1) Dimensions Few-Body Syst. (IF 1.6) Pub Date : 2024-02-16 Salvatore De Vincenzo
Theoretically, in (1 + 1) dimensions, one can have Klein–Fock–Gordon–Majorana (KFGM) particles. More precisely, these are one-dimensional (1D) Klein–Fock–Gordon (KFG) and Majorana particles at the same time. In principle, the wave equations considered to describe such first-quantized particles are the standard 1D KFG equation and/or the 1D Feshbach–Villars (FV) equation, each with a real Lorentz scalar

Abstract We examine the spatial distribution of electric charges within an extended, non-conductive cylinder featuring an inner radius denoted as \(r_{0}\) . Our investigation unveils the emergence of a distinct modified attractive-inverse square potential, arising from the intricate interplay between the electric field and the induced electric dipole moment of a neutral particle. This modified potential

A computational method is proposed to calculate bound and resonant states by solving the Klein–Gordon and Dirac equations for real and complex energies, respectively. The method is an extension of a non-relativistic one, where the potential is represented in a Coulomb–Sturmian basis. This basis facilitates the exact analytic evaluation of the Coulomb Green’s operator in terms of a continued fraction
