  • In this thesis the experimental results on the Na/sup 23/(d p)Na/sup 24/ reaction at a deuteron energy of 7.8 Mev were shown and the nuclear structure of Na/sup 24/ was discussed. The ButlerBorn Approximation analysis and the Distorted-Wave Born approximation analysis for the description of the angular distributions of the protons emerging from the reaction were dealt with in the first chapter. Chapter two presents the experimental results of angular distributions of protons from transitions to levels of Na/sup 24/ in a region of excitation of 0 to 7 Mev. In the third chapter the interpretation of the nuclear structuremore » of Na/sup 24/ on the basis of the experimental results leads to the conclusion. that the unified model with pairing force and two-body interactions from the central force, the spin-orbit force, and the Sensor force between the old proton and the odd neutron may describe the nuclear structure of Na/sup 24/.

  • The 3K cosmic background radiation (CBR), believed to be the signature of the initial singularity in ''big bang'' cosmologies, is a fundamental tool for understanding the structure of the early universe. Here a measurement of the spatial anisotropy of this radiation at a sensitivity of 6 parts in 10/sup 5/ is described. The observations were carried out in a balloon-borne package using three room temperature, correlation-type microwave radiometers, with 500 MHz bandwidths centered at 24.8, 31.4 and 46.0 GHz. The achieved system noise temperatures for the three receivers is 800K. Three flights between August 1978 and July 1980 cover themore » entire northern hemisphere sky, allowing for tests of both dipole and higher order anisotropies. A dipole effect is detected at the 4 mK level with heliocentric equatorial components (T/sub x/, T/sub y/, T/sub z/) = (-3.80, 0.63, -0.25) + (0.21, 0.20, 0.21)mK. If this is interpreted as a purely kinematic effect, the data imply a solar velocity of 410 + 20 km/sec towards ..cap alpha.. = 11.4 + 0.2 hours, delta = -3/sup 0/ + 3/sup 0/ relative to the CBR reference frame. The temperature spectral index of the dipole is determined to be -0.09 + 0.20, confirming that the radiation, in this frequency range, is that of a blackbody. No quadrupole anisotropy is present in the data, which place a 90% confidence upper limit of 0.4 mK on the quadrupole magnitude.« less
  • A method was developed to produce a beam of /sup 9/Be/sup +/ ions from a CN Van de Graaff. Absolute cross sections were measured for elastic scattering of /sup 9/Be on /sup 9/Be at laboratory energies of 5, 9, 12, and 16 MeV. These differential cross sections were fit with a computer code to ascertain optical-model parameters. Absolute differential cross section angular distributions for /sup 9/Be(/sup 9/Be, (/sup 1/P, /sup 3/T, /sup 4/..cap alpha..))(/sup 17/N, /sup 15/N, /sup 14/C) reactions were measured for 5 and 12 MeV laboratory energies. Fits to the reaction data were made using a finite-range recoilmore » DWBA computer code.« less
