States in ('14)C and ('14)N have been populated using the lithium induced reactions: ('10)B(('6)Li,d)('14)N, ('11)B(('6)Li,t)('14)N, ('11)B(('6)Li,('3)He)('14)C, ('11)B(('7)Li,(alpha))('14)C, ('12)C(('6)Li,(alpha))('14)N, ('13)C(('7)Li,('6)He)('14)N, and ('13)C(('7)Li,('6)Li)('14)C at bombarding energies between 20 and 34 MeV. States in the residual nuclei were populated selectively in these reactions, as a result of both the states' configurations and their spins. Experimental angular distributions for the ('11)B(('7)Li,(alpha))('14)C, ('11)B(('6)Li,('3)He)('14)C, and ('11)B(('6)Li,t)('14)N reactions were taken at ('7)Li and ('6)Li bombarding energies of 34 MeV. / Comparison of the results for the one, two, three, and four particle transfer reactions to excited states in ('14)N performed here allowed structure information to be obtained for levels in ('14)N. Similarly, the one and three particle transfer reactions to states in ('14)C were compared with states populated by two nucleon transfer. When these results were compared with medium energy inelastic scattering data, these reactions were shown to provide complementary information on high-lying states in the A = 14 mass region. / The usefulness of a DWBA description of the multi-nucleon transfer process was demonstrated through the ability of DWBA to fit the angular distributions and provide information on the parities and spins of the final states. Some limits on the spins of the final states could also be deduced from compound nucleus calculations and their comparisons with the experimental cross sections. / Experimental criteria were developed based on the population of states by the ('11)B(('6)Li,('3)He)('14)C and ('11)B(('6)Li,t)('14)N reactions to known analog states in order to assign high-lying isobaric analog (T = 1) states in ('14)N and ('14)C. The criteria were: the comparisons of differential cross sections, angular distributions, analog energies, and population by other reactions. From these criteria, T = 1 states in ('14)N were identified to 18 MeV excitation. / Source: Dissertation Abstracts International, Volume: 45-01, Section: B, page: 0241. / Thesis (Ph.D.)--The Florida State University, 1984.
