Abstract
The relaxation of the isoscalar giant monopole resonance (GMR) in the hot nuclei produced in heavy-ion reactions is discussed based on the B oltzmann-Nordherin-Vlasov equation, The oscillation of the GMR in the spherical hot nuclei is isotropic, The GMR energy calculated is approx imately equal to that resulting from the formula E(GMR) = 80A(-1/2). T he nucleon collision and the particle escape are the dominant reasons for the relaxation of the GMR in the hot nuclei.
