APPROXIMATE VALUE OF SOME ELECTRIC QUADRUPOLE MOMENTS OF NUCLEI WITH MASS A /gt/ 218 (in French)
The Bohr-Mottelson formula was used to estimate the quadrupole moments and half life of the 2+ level in the region A < 218 from the alpha - gamma angular correlations under the supplementary hypotheses that the recoil nucleus is stopped when it emits gamma radiation and that the elec- tric field gradients of the chlorides and nitrates of these elements are identical. The results obtained for Rn/sup 220/ , Rn/sup 222/, Ra/sup 224/, Ra/sup 226/, and U/sup 234/ agree with approximately the values obtained by direct measurement. Therefore, the process was applied to Rn/sup 218/, Ra/sup 222/, Th/sup 226/, Th/sup 228/, Th/ su p 232/, and U/sup 236/. The results of the approximation are tabulated. (J.S.R.)
