Threshold electron impact spectra have been obtained for helium, neon, argon, krypton, xenon and carbon monoxide using a velocity-selected electron beam. Zero energy electrons ejected at excitation thresholds are scavenged by sulfur hexafluoride and the resulting SF(6)¯ ions are detected using a mass filter. Optically forbidden transitions are observed to make a large contribution to the total threshold excitation. Singlet-triplet transitions are especially prominent in helium and carbon monoxide. Excitation of outer s and p electrons is observed for neon, argon, krypton and xenon. / Science, Faculty of / Chemistry, Department of / Graduate

<p>The nearly oblate deformed Au nuclei show rotational bands built on multi quasiparticle excitations [Bou89, Bou92, Gue03, Gue01, Ven92]. Several of these bands are built on rotationally aligned high-j proton and neutron excitations. In many cases bands consisting of two or three signature partner E2 sequences are observed. For some fo these bands signature inversion is found and this feature gives a great challenge to the theoretical models. In this study the researcher performed TRS and CSM calculations for all high-j rotational bands in the p186-194s Au nuclei aiming to predict the signature splitting and inversion phemomena, alignments, gains in alignments, gains in alignment and band crossing frequencies observed.</p>
