摘要
本文用无波函数微扰论(Perturbation theory Without wavefunction)计算了以U_c(γ)=1/2kγ~2+λ_1γ~4+λ_2γ~6+C为囚禁势的重夸克偶素能谱,选取适当的势参数时,粲偶素族和底偶素族的计算值与实验结果相符合,同时还利用计算能谱时所选取的势参数算出了与各能级相对应的平均半径,<γ~2>及<γ~4>等值。
The heavy quarkonium spectra were analysed with a phenomenological confinement potential of the form U_c(r)=1/2k_(r^2)+λ_1r^4+λ_2r^6+C using perturbation theory without wavefunction. With choice of suitable parameters, we calculated the binding energy levels of c■ and b■ systems which provide good agreement with experimantal values.
