K-conversion coefficients for gamma transitions in Dy160 have been measured and the transition multipolarities determined as follows (Eγ, αK, multipolarity): 86.7 kev, 1.5 (E2); 197 kev, 1.6 × 10−1 (E2); 216 kev, 4.0 × 10−2 (E1); 299 kev, 1.3 × 10−2 (E1); 880 kev, 3.1 × 10−3 (E2); (962 + 966) kev, 2.5 × 10−3 (E2); 1179 kev, 6.6 × 10−4 (E1); 1205 kev, 4.6 × 10−4 (E1); 1273 kev, 6.1 × 10−4 (E1); 1315 kev, 3.9 × 10−4 (E1), Relative transition intensities are compared with the predictions of the Unified Model of Bohr and Mottelson and the asymmetric rotor theory of Davydov and Filippov. Transition intensities from the 966-kev level to members of the ground state rotational band suggest the asymmetric rotor interpretation.

Coincidence Measurements

States in the transitional nucleus, 151Gd, excited by the (α,2n) reaction have been studied by gamma-ray and conversion electron measurements. Gamma-ray energies, intensities, excitation functions, and γ–γ coincidence measurements were used to establish the levels populated. Angular distributions involving measurements at seven angles from 0° to 90° and K-conversion coefficients have been used to make spin and parity assignments.The El character of the 65, 79, 340, 358, 406, and 462 keV transitions, which in the absence of K-conversion data had been tacitly assumed to be M1 by earlier workers leads to a significant revision of their parity assignments and interpretation of the level structure. The negative parity states at 1210, 1463, 1726, 2004, 2295, 2600, 2915, and 3237 keV form a well-developed rotational band based on the 11/2− [505] state at 1210 keV. The properties of this band in this nucleus are compared with those of the same band in a number of nearby nuclei. Two non-interacting negative parity bands with states at 0(7/2−), 706(11/2−), 1435(15/2−), 2078(19/2−), and 379(9/2−), 902(13/2−), 1511(17/2−), 2297(21/2−), respectively, have been found, as well as a number of other negative parity states of spin 7/2, 9/2, and 13/2. A complex positive band structure involving states at 784(11/2+), 852(13/2+), 1116(13/2+), 1346(17/2+), 1364(15/2+), 1677(17/2+), 1851(19/2+), 1853(21/2+), 2197(21/2+), 2325(23/2+), and 2405(25/2+) has been identified. By using a somewhat unusual set of parameters, we have been able to approach a description for the positive parity states in terms of the triaxial model of Meyer-ter-Vehn.

Acetone transformation catalyzed by HZSM-5 and NaZSM-5 zeolites and by zeolites modified with basic oxides was studied in an integral reactor at a temperature of 350 °C. Modification of acido-basic properties of ZSM-5 zeolites resulted both in the total conversion changes and in the essential changes in the product composition. Isobutene was found to be the main product over HZSM-5 zeolites exhibiting low activity, while aromatics prevailed when high conversion level was attained. Classical condensation of acetone yielding mesityloxide and phorones was observed over NaZSM-5 zeolites impregnated with CaO and ZnO.
