| 英文摘要 | An earlier study of unusual electromagnetic decays in {sup 86}Zr was extended in order to make comparisons with its isotone {sup 84}Sr and with {sup 84}Zr. The K=14 (t {sub {1/2}} = 70 ns) high-spin isomer in {sup 176}W was found to have a 13% branch directly to the K=O ground-state band, one of the strongest violations of K-selection rules known. A new program to search for a predicted region of oblate deformation involving neutron deficient isotopes in the Rn/Fr/Ra region was begun. In the area of nuclear astrophysics, as part of a study of the onset of the rp-Process, a set of measurements searching for possible new resonances for {sup 14}O+{alpha} and {sup 17}F+p reactions was completed and a coincidence experiment measuring the {sup 19}F({sup 3}He,t){sup 19}Ne({alpha}){sup 15}O and {sup 19}F({sup 3}He,t){sup 19}Ne(p){sup 18}F reactions in order to determine the rates of the {sup 18}F(p,{alpha}){sup 15}O and {sup 18}F(p,{gamma}){sup 19}Ne reactions was begun. Experimental measurements of {beta}n{alpha} coincidences from the {sup 15}N(d,p){sup 16}N({beta}{sup {minus}}{nu}){sup 16}O({alpha}){sup 12}C reaction have also been completed and are currently being analyzed to determine the rate of the {sup 12}C({alpha},{gamma}) reaction. In the APEX collaboration, we have completed the assembly and testing of two position-sensitive Na barrels which surround the axial silicon detector arrays and serve as the e{sup +} triggers by detecting their back-to-back annihilation quanta were completed. The HI@AGS and RHIC collaborations, construction and implementation activities associated with the space-time-tracker detector and in the design of the central detector for the PHENIX experiment were carried out. Operation of the ESTU tandem accelerator has been reliable, delivering beam on target at terminal voltages as high as 19.3 MV and running for as long as 143 days between tank openings. Fabrication and bench testing of a new negative ion source system have been completed. |
