A quantal harmonic vibration in a spherical nucleus is assumed to couple to the nucleonic motion through a particle-phonon interaction. The dynamics of both the collective mode and the heat reservoir are analytically described and numerically solved in a range of physically significant interaction strength and duration. The competetion between diffusive and dissipative processes in the course of evolution towards equilibration is described. © 1984.
