THE U8-21 MEV REGION OF CARBON-12 POPULATED BY BORON-11 (DEUTERON,NEUTRON) CARBON-12 AT E(DEUTERON) = 10 AND 12 MEV

Unknown Date (has links)
The modified high resolution beam pulsing system at FSU has been used for neutron time of flight detection over relatively short flight paths (2 m). This enabled a study of ('12)C using the (d,n) proton stripping reaction. In addition to the well known lower lying states three strong peaks, at 18.38 ((GAMMA) = 0.350), 19.55 ((GAMMA) = 0.575), 20.62 ((GAMMA) = 0.525) MeV excitation, were seen in the measured energy angular distribution spectra. Each peak likely contains more than one state in ('12)C. Angular distributions were compared with distorted wave Born approximation calculations for particle unbound states. A coincidence experiment measured the branching ratios and angular correlations of the charged particle decays. The 19.55 MeV peak was clearly shown to be composed of at least two states with different proton and alpha decay strengths. The 18.38 and 20.62 MeV peaks were shown to contain states of natural parity. The angular correlations were compared to theoretical calculations for various angular momentum possibilities. The singles spectra of the present work most closely resemble those of intermediate energy proton inelastic scattering. / Source: Dissertation Abstracts International, Volume: 45-09, Section: B, page: 2969. / Thesis (Ph.D.)--The Florida State University, 1984.

NUCLEAR SPECTROSCOPY OF YTTRIUM (90) AND NIOBIUM (92)

Unknown Date (has links)
Levels in ('90)Y were studied using the ('91)Zr(t,(alpha))('90)Y and ('89)Y(n,(gamma))('90)Y reactions. The results of these studies were used to locate the members of the (pi)(p1/2)('1) (upsilon)(d5/2)('1), (pi)(g9/2)('1) (upsilon)(d5/2)('1), (pi)(p3/2)('-1) (upsilon)(d5/2)('1), and (pi)(f5/2)('-1) (upsilon)(d5/2)('1) configurations. Of particular interest is the anomalously high energy of the 0- state of the (pi)(f5/2)('-1) (upsilon)(d5/2)('1) multiplet. In addition to this several new low spin levels were discovered in the ('89)Y(n,(gamma))('90)Y reaction. / The structure of ('92)Nb was investigated by the ('91)Zr(('3)He,d)('92)Nb reaction. The members of the (pi)(g9/2)('1) (upsilon)(d5/2)('1) configuration were strongly populated and have spectroscopic factors with simple 2J(,f)+1 structure. Several states are populated with (,p) = 1 angular distributions. Also a large portion of the (,p) = 2 spectroscopic strength is observed to be fragmented over many T(,<) states. / The energy spectra of ('90)Y and ('92)Nb were calculated using finite-range matrix elements including both central and tensor potentials. The tensor force is found to have a large effect on the low spin negative parity states of ('90)Y. / Source: Dissertation Abstracts International, Volume: 41-03, Section: B, page: 1008. / Thesis (Ph.D.)--The Florida State University, 1980.

CORIOLIS-DECOUPLED HIGH-SPIN E2 BANDS IN ODD-A RUBIDIUM AND KRYPTON ISOTOPES

Unknown Date (has links)
Heavy-ion reactions have been used to study high-spin bands in odd-A nuclei in the mass A (TURNEQ) 80 region. A previously unobserved band of E2 transitions has been assigned to ('79)Rb. Six reactions were used to rule out other assignments. Bands of E2 transitions have also been assigned to ('79)Kr and ('81)Kr. The bands in ('79)Rb, ('79)Kr and ('81)Kr were studied using (gamma)-ray singles, (gamma)-(gamma) coincidence, angular distribution, and excitation function measurements. Relative reaction cross sections were deduced for the ('10)B + ('72)Ge and ('11)B + ('73)Ge reactions at 40 MeV. The experimental cross sections were in fair agreement with evaporation-model calculations made with the code ALICE. / The ('79)Rb band was compared with the ('81)Rb decoupled band. These bands were interpreted using the RAC (rotation-aligned coupling) model as arising from the decoupling of a g(,9/2) proton from the ('78)Kr and ('80)Kr cores, respectively. The ('79)Kr and ('81)Kr bands were interpreted as arising from the partial decoupling of g(,9/2) neutrons from the ('78)Kr and ('80)Kr cores, respectively, and a comparison was made with the ('77)Kr band. The amount of decoupling in the Rb isotopes was compared to that in the Kr isotopes. / Source: Dissertation Abstracts International, Volume: 41-11, Section: B, page: 4162. / Thesis (Ph.D.)--The Florida State University, 1980.
