| 摘 要： | 用BNV方程讨论了中能重离子反应形成的热核单极巨共振(GMR)的驰豫过程.计算表明,球形热核GMR振荡是各向同性的,共振能与EGMR=80A－1/3公式给出的数值基本一致.核子碰撞和粒子逃逸是引起热核GMR阻尼衰减的主要原因.

| Abstract: | The relaxation of the isoscalar giant monopole resonance (GMR)in hot nuclei produced in heavy-ion reaction is discussed in the frame of the Boltzmann-Nordherin-Vlasov equation.The oscillation of the GMR in the spherical hot nuclei is isotropic.The calculated GMR energy is approximately equal to that resulting from the formula EGMR=80A-1/3.The nucleon collision as well as the particle escape are the dominant reasons of the relaxation of the GMR in the hot nuclei. |
