Abstract
Extensive isotope shifts measurements in the 3910-9160 Å region of the plutonium spectrum were made. This enables us to determine with precision the value of the Relative Isotope Shift (R.I.S.) between the 244-242 and 242-240 couples of isotopes. The value found for the R.I.S. is 1.03 ± 0.02. Based on the optical R.I.S. of the plutonium isotopes (from 238 to 244) the inherent quadrupole moments of the odd isotopes were determined, using the known values of the quadrupole moments of the even isotopes (deduced from Coulomb excitation). They were found to be respectively equal (in barns) to: Q239 = 11.3 ± 1.0, Q241 = 11.5 ± 0.5, Q243 = 11.6 ± 0.5.
