n particles in the 11.5-13.5 MeV energy range have been employed to Coulomb excite the 2" members of the p-vibrational band of nine even-even nuclei in the 158 «A «186 mass region. The B (E2, 0' -2")values were then determined by energy analyzing the backscatered projectiles The results for 158& i600d i8 & $64Dy &86& 188, 170Er and 184, 186% are 0.106 + 0.015, 0.104+ 0.004, 0.130+ 0.005, 0.121+0.005, 0.140+ 0.006, 0.130+ 0.005, 0.107+ 0.006, 0.138+ 0.006, and 0.139+0.004 (etb2), respectively.

Elastic and inelastic scattering of ' 0 on "Mg was performed at incident energies between 20 and 42 MeV.The data are analyzed in terms of coupled channel calculations.NUCLEAR REACTIONS "Mg('60 60'), E =20-42 MeV; measured 0(E, 0= 51.7'), o (8 = 42 Me V, 0) coupled channel calculation .
