Properties of Skyrme force as a residual interaction in beyond-mean-field theories

چکیده
Abstract In an effort to find effective interaction that can consistently be used for both the mean-field part and residual in beyond-mean-field theories, properties of Skyrme interactions as a are investigated. The time-dependent density-matrix theory (TDDM) is ground states $^{16}$O $^{40}$Ca calculated using five standard parametrizations interaction, which differ density momentum dependence. It found has strong dependence weak dependence, induces substantial ground-state correlations comparable results other theoretical calculations.

Skyrme Mean-Field Study of Rotational Bands in Transfermium Isotopes
Self-consistent mean field calculations with the SLy4 interaction and a densitydependent pairing force are presented for nuclei in the Nobelium mass region. Predicted quasi-particle spectra are compared with experiment for the heaviest known odd N and odd Z nuclei. Spectra and rotational bands are presented for nuclei around 252,4No for which experiments are either planned or already running.

the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...

Since its first use in Hartree-Fock calculations in 1972, the Skyrme Force, which includes around ten free parameters to be fitted to data, has undergone many such fitting procedures to different sets of data. To date there have been more than 200 parameter sets published. Since the Skyrme force can be thought of as an expansion of an in principle exact density functional, the Skyrme force has ...
