I do not know what inspires me to use geometric shapes in my artwork. It may have started when I took my first jewelry and metalworking class in college. For one assignment, I had to find an artist and make an artwork that was inspired by his artworks. I choose is Sol Lewitt because I simply liked his opened cubes. Since I started studying in Jewelry and Metalwork and Sculpture at the University of Iowa, I my artworks are still based on geometric shapes. I enjoy them because they are shapes that I see around me everyday; such as textbooks, chairs, doors etc. In my thesis, I will explain my artworks and the techniques that I used, why I made them, what inspired me. My first semester, I just made containers which were based on geometric shapes. After that my ideas and concepts evolved to a simple object based on geometric shapes with no function. A simple geometric object without a function is better for exploring beautiful geometric. Firstly, I find a subject that I can use my ideas and concepts on. It can be something that I see everyday such as myself, faucet, jewelry etc. Sometimes, I find an interesting thing in textbooks, magazines and catalogs. Other times, I find them when I buy materials for my artworks; just shopping at the hardware. There are many things around me that I could use to create my artworks. I just choose some of them to make art and finish assignments.

Relative lifetimes, and the closely related quadrupole moments (Q[subscript]i values), of the six superdeformed (SD) bands in �������Hg and the yrast SD band in �������Hg were determined by a Doppler-shift attenuation method measurement. The experiment was performed using the Gammasphere array and Lawrence Berkeley National Laboratory's 88-inch Cyclotron. The Q[subscript]i values, which are a sensitive probe of the nuclear shape, of all the �������Hg SD bands were found to be similar. This is the first accurate determination of the Q, values of SD bands in an odd-A nucleus in the mass-190 region. Additionally, evidence is presented for an unexpected difference in the Q[subscript]i values of the �������Hg and �������Hg SD bands. There is an indication that the Q[subscript]i value of the �������Hg yrast SD band is approximately 15 percent greater that the Q[subscript]i values of the �������Hg SD bands. The results provide information on the shape-driving effects of orbitals in the mass-190 region and imply that the deformations of bands with identical transition energies are not necessarily the same. / Graduation date: 1997

The high-spin states of the nucleus ⁷²Ge were populated via the ⁷°Zn(a,2n)⁷²Ge fusion-evaporation reaction at a beam-energy of 30 MeV. The ')'-decays were observed with the AFRODITE spectrometer array at iThemba LABS (Faure, South Africa). Twenty-seven new transitions, 18 new levels and 2 new bands were added to the ⁷²Ge level scheme, and several corrections were made to t he previously-known level scheme. Transitions were characterised using Directional Correlation from Oriented states (DCO) and polarisation measurements, and spin-parity assignments were made for 7 new levels. Spin and parity were also reassigned to a previously-known structure. One of the new bands was ident ified as part of an octupole-vibrational band. No tetrahedral states were observed in the scheme despite N = 40 and Z = 32 having been identified as tetrahedral magic numbers. The meaning of the new 14⁺ yrast level for the underlying structure of the ground state band is discussed
