Scalar-isoscalar states, gravitational form factors, and dimension-2 condensates in a large-Nc Regge approach
Scalar-isoscalar states gravitational form factors dimension-2 condensates
2011/1/7
Scalar-isoscalar states are analyzed within the large-Nc Regge approach. We find that the lightest f0(600) scalar-isoscalar state fits very well into the pattern of the radial Regge trajectory. We con...
Isoscalar dipole coherence at low energies and forbidden E1 strength
Isoscalar dipole coherence low energies forbidden E1 strength
2010/12/29
In 16O and 40Ca an isoscalar, low-energy dipole transition (IS-LED) exhausting approximately 4% of the isoscalar dipole (ISD) energy-weighted sum rule is experimentally known, but conspicuously absent...

从扩展Skyrme力的HF能量密度H(r)出发,利用半经典近似下动能密度泛函τq[ρn,ρp]及自旋-轨道密度泛函Jq[ρn,ρp],得到了核系统的能量密度泛函H[ρn,ρp]在给定核子数条件下对此泛函作变分计算使我们确定了核的基态密度分布,由此研究了原子核的静态及isoscalar巨共振性质.所有结果同实验及HF(RPA)计算结果很好一致.
Longitudinal Form Factor of Isoscalar Particle-Hole States in 16O, 12C and 40Ca with M3Y Interaction
Longitudinal Form Factors Random Phase Approximation (RPA) Collective Model and M3Y
2010/4/9
Longitudinal form factors of the low-lying, T = 0, particle-hole states of 16O, 12C and 40Ca are studied in the framework of Random Phase Approximation RPA. The basis of single particle states is cons...
Binding Energies of Isoscalar and Isovector Ground States of N=Z Nuclei in the Interacting Boson Model
Isoscalar and Isovector Ground States N=Z Nuclei the Interacting Boson Model
2010/10/28
An algebraic model is developed to calculate the T = 0 and T = 1 ground-state binding energies of N = Z nuclei in the 28-50 shell which is currently the object of many experimental studies.
