[en] In order to investigate whether new nuclear structure information can be obtained from studying the direct transfer of more than two nucleons using heavy-ion projectiles, we have investigated the ²⁸Si(¹⁶O,¹²C)³²S and ¹²C(¹⁴N,d)²⁴Mg reactions as candidates for the direct transfer of four- and twelve-nucleons, respectively. The counter telescope-position sensitive detector kinematic coincidence method--both angular distributions (22⁰ less than theta/sub L/ less than 95⁰, E/sub L/ = 55.54 MeV) and excitation functions (theta/sub L/ = 26⁰, 50 less than E/sub L/ less than 63 MeV) were obtained for strongly excited states below 10 MeV in excitation in the first reaction. For the ¹²C + ¹⁴N interaction, a measurement of the angular distributions (25⁰ less than theta/sub L/ less than 140⁰, E/sub L/ = 20,25 MeV) for proton, deuteron and alpha-particle emission to many low-lying states sufficed for the present purposes. Comparison of Hauser-Feshbach statistical model calculations with these data indicated that the light-particle production from the ¹²C + ¹⁴N interaction as investigated here is predominantly compound nuclear in nature. The selectively strong population of a few states in ³²S by the ²⁸Si-(¹⁶O,¹²C)³²S reaction is primarily direct. The structure of these states was deduced from available light-ion-induced transfer reaction studies and shell model calculations; the importance of shell model configurations is indicated, and an alpha-particle transfer model can not account for the observed selectivity. Calculations of the ²⁸Si(¹⁶O,¹²C)³²S reaction with a microscopic multinucleon transfer code indicate selectivities consistent with the present results. Moreover, the calculations suggest the presence of other, unexpected selectivities, all of which may be understood on a physical basis, and some of which appear as an extension of a similar effect seen in two-nucleon transfer reactions

[en] This book presents the following experimental and theoretic reviews on the application of relativity and the inclusion of quark degrees of freedom; experimental results in nucleon-nucleus physics; theoretical talks on hadronic interactions and collective spin modes of excitation; and talks presenting data for nuclear spin observables. The book contains papers on microscopic relativistic description of nucleon-nucleus scattering, the relativistic nuclear many-body problem, antiproton annihilation at rest in nitrogen and argon, polarized proton experiments at TRIUMF, and nuclear medium correction to the free hadron-hadron interaction. High nuclear temperatures by antimatter-matter and the study of isovector giant resonances in hadrons are also discussed

[en] The study of intermediate-energy proton inelastic scattering to one-particle one-hole states has attracted considerable attention over the last few years. One primary purpose of these studies has been to exploit the structural simplicity of these excited states as a possible means of separating effects due to nuclear structure and those due to the reaction mechanism. Several excellent review talks have surveyed many of the current experimental and theoretical investigations. The energy dependence of proton inelastic scattering is investigated. In recent years, high-quality inelastic scattering data for several transitions have become available over a wide range of incident energy. In addition, there are now available several models of the effective nucleon-nucleon interaction and several prescriptions for making predictions of inelastic scattering. 17 references, 16 figures

[en] Angular distributions were measured for elastic and inelastic scattering of 45- and 75-MeV ¹⁶O by ⁴⁰Ca. DWBA and coupled-channels calculations were performed. The two calculations produced similar results for elastic scattering. For inelastic scattering, the latter agreed well with the data at the higher energy, but significant discrepancies existed at the lower

[en] Spins of three new states in ¹⁶O in the 21 to 24 MeV excitation region were observed in the ¹²C(²⁰Ne, ¹⁶O)¹⁶O reaction at incident energies between 150 and 294 MeV

[en] Fusion cross sections for the ¹⁴N + ¹²C reaction were measured at higher energies (248 and 158 MeV). Measured and calculated yields for Z = 5 to 11 evaporation residues are compared, and values of the critical angular momentum are plotted against excitation in ²⁶Al. The deduced maximum for this quantity was 27.5 h-bar. 2 figures

[en] Production of the neutron-rich nucleus ¹¹Li in the bombardment of ²³²Th by ¹¹B at 114 MeV suggests that multinucleon transfer reactions induced by neutron excess heavy ions on heavy targets present a feasible method of measuring the mass excess of exotic light nuclei in the limit of stability

[en] The authors have measured the angular distributions and analyzing powers for polarized proton scattering from ²⁶Mg at 135-MeV incident energy at the Indiana University Cyclotron Facility. Angular distributions were measured in 5⁰ steps from a laboratory angle of 10⁰ to 60⁰ for states in the excitation energy range from 0 to 20 MeV. Five 6^- states have been identified based on the characteristic angular distributions of the cross sections and analyzing powers at 9.17-, 11.98-, 12.48-, 12.85- and 18.05-MeV excitation energy
