Transition density of the octupole vibration in 208Pb. Comparison of theory and experiment

The transition charge density for lead 208 was calculated using random phase approximation calculations and is shown. It has a large peak centered at the nuclear surface at abour r = 7fm and pronounced oscillations in the interior of the nucleus for 0 less than or equal to r less than or equal to 5 fm. With the hydrodynamic or the Tassie model the transition density can be related to the ground state charge density. It is noted that the fluctuations in the ground state charge density are not at all large enough to explain the observed oscillations. The structure of this transition strength is described. A comparison is given of experimental data for sigma/sigma/sub Mott/ to theoretical predictions for the 3- state in 208Pb. 14 references
