同位旋标量 meaning in Chinese

isoscalar

Examples

  1. Using the fully consistent rrpa method , we have studied the properties of collective multipole excitations for several closed - shell and closed sub - shell nucleus in the isoscalar modes and isovector modes
    计算结果显示,从fermi海核子态到dirac海负能核子态形成的对激发在核的集体激发中的贡献很重要,尤其是对核的同位旋标量激发模式。
  2. The results indicate that the effects of the dirac sea states are pronounced in the collective multipole excitations for nuclei , especially on the isoscalar giant modes , but become weaker for light nuclei , while the contributions on the isovector modes are negligible
    在核的同位旋标量激发模式中, dirac海负能核子态在不同的共振模式中的贡献程度不一。对于同一种激发模式, dirac海负能核子态的贡献随着核子数的减少而变弱。
  3. At the other hand , we can perform the rrpa calculation with the continuum replaced by a set of outgoing single particle resonances , it indicates that the resonances in the continuum play an important role in the description of nuclear dynamical processes , such as collective giant resonances . energies , widths and wave functions of the single particle resonant continuum are determined by solving scattering states of the dirac equation with proper asymptotic conditions for the continuous spectrum in the r ' elativistic mean field theory . the relativistic regular and irregular coulomb wave functions are calculated numerically
    在进行相对论无规位相近似计算时将连续谱中所有的正能态用单粒子共振态来代替,并且在计算中采用单粒子共振态的真实宽度,利用这种方法我们计算了核的同位旋标量巨八极共振响应函数,并且和考虑了连续谱中所有正能态贡献的结果进行比较,计算结果表明,连续谱中只考虑单粒子共振态对核的集体激发的贡献时,给出的响应函数基本上能够重现考虑了所有正能态贡献时的计算结果,这说明了在核的集体激发中,连续谱中主要是单粒子共振态的贡献。
  4. The results show that binding energies per nucleon at each density and various asymmetry parameters fulfill the empirical parabolic law and the asymmetry energy is density dependent . it is found that both scalar and vector potentials of neutron in the neutron rich nuclear matter become stronger although the isospin dependence is not stronger . we compare our results with those in a simple method , where the dbhf nucleon self - energies are extracted from the momentum dependence of the single - particle energy
    首先我们要求在每一个密度及各种不对称系数的核物质中,相对论平均场( rmf )计算出的核子标量与矢量自能与dbhf计算出的标量与矢量自能一致,从而得到在rmf下的密度依赖的有效介子核子耦合常数,包括同位旋标量介子。
