- 中文摘要： 本文利用簡階夸克模型分析介子之質譜“介子波動函數假定含有徑向激發簡階振盪態。π介子之第一徑向激發態之質量為1340 McV.此介子須在5π共鳴態中證實。ρ介子之第一徑向激發態之質量為1530 McV.其角動量激發態之質量為1410 MeV.此與新發現之u' (1500)共嗚子之質量相符。實驗上己確定之E(1420)與ω(1675)二粒子各為η介子及ψ介子之第一徑向激發態。
- 英文摘要： A spectroscopic analysis of mesons is carried out within the frameworkof the harmonic oscillator quark model, in which the configuration mixingof radially excited harmonic oscillator states in meson wave functions isconsidered. The first radially excited state of the π meson is predicted at1370 MeV, which could be a 5τ resonance. The recently observed ρ' (1500)resonance bump is speculated to consist of a radially excited state of the ρmeson at 1530 MeV and an orbitally excited state at 1410 MeV. The longobserved E (1420) and。，(1675) are identified as the first radially; excitedstates of the η and ψ mesons respectively.
