COULOMB EXCITATION OF Ge$sup 74$ AND Ge$sup 7$$sup 6$
Deuterons and protons with energies from 3.5 to 4.0 Mev were used to excite the 598 kev level in Ge/sup 74/ and the 564 kev level in Ge/sup 76/. The scattered particles were studied at angles from 75 to 150 deg with a magnetic analyzer by using photographic plate detection. The applicability of Coulomb excitation theory in this region of atomic number and incident energy was tested by measuring the energy dependence of the deuteron excitation cross sections for both nuclei, the angular distribution of inelastically scattered deuterons for Ge/ sup 74/, and the ratios of the deuteron to the proton excitation cross sections. These data indicate that Coulomb excitation theory may be applied for deuterons of less than 3.5 Mev and protons of less than 4.0 Mev. The values of the reduced transition probability, B(E2), of Ge/sup 74/ and Ge/sup 76/ are 0.32 plus or minus 0.03 and 0.29 plus or minus 0.03, respectively. The B(E2) value derived from 4.0-Mev deuteron data for Ge/sup 74/ was 30% higher than the above value. Part of this discrepancy may be due to departures from Rutherford scattering of the elastically scattered deuterons since Hutherford scattering was assumed in deriving the inelastic cross sections.
