Dubovichenko Categories: nucl-th Comments: 247 p Report-no: 25-06-10 \\ Monograph includes the results of the scientific work of the author for approximately 10 years and it is dedicated to theoretical studies of the structure of light atomic nuclei on the basis of potential cluster model with the forbidden states. Are examined questions of the single-valued construction of the intercluster potentials, which contain the forbidden states and simultaneously applied in the continuous and discrete spectra for the light nuclear systems with a mass of from 2 to 16. Is presented the mathematical apparatus and some calculation methods, utilized in the cluster model. Many questions, until now, considered here did not be reflected in the monographic literature. The book can represent interest for the students of elder courses, probationers, graduate students and scientific workers, who work in the field of theoretical nuclear physics. This Book is written in Russian, but will perhaps present certain interest. \\ ( http://arxiv.org/abs/1006.4944 , 2546kb) ------------------------------------------------------------------------------ \\ arXiv:1006.4947 Date: Fri, 25 Jun 2010 09:53:16 GMT (1952kb) Title: Calculation methods of the nuclear characteristics Authors: S.B. Dubovichenko Categories: nucl-th Comments: 311 p Report-no: 25-1-06-10 \\ In the book the mathematical methods of nuclear cross sections and phases of elastic scattering, energy and characteristics of bound states in two- and three-particle nuclear systems, when the potentials of interaction contain not only central, but also tensor component, are presented. Are given the descriptions of the mathematical numerical calculation methods and computer programs in the algorithmic language "BASIC" for "Turbo Basic" of firm "Borland" for the computers of the type IBM PC AT. For the numerical solutions of the initial Schroedinger equations are used finite- difference and variational methods, and also method of Runge-Kutta with the automatic calling sequence on the assigned accuracy of results for the scattering phase shifts and binding energy. Is given the description not of the standard methods of solving the system of equations of Schroedinger to the bound states and the alternative to Schmidt's method, method of solution of the generalized matrix problem at the eigenvalues. The developed programs make it possible to determine the wave functions of relative motion of nuclear fragments, calibrated to the correct asymptotic behavior taking into account Coulomb interaction. The programs of the extraction of nuclear phases (phase shift analysis) from the differential elastic cross sections are given. The book can be used as the textbook according to the numerical mathematical methods for the students and the graduate students of the physical and mathematical specialties of higher educational institutions. This Book is written in Russian, but will perhaps present certain interest. \\ ( http://arxiv.org/abs/1006.4947 , 1952kb) ------------------------------------------------------------------------------ \\ arXiv:1006.5018 Date: Fri, 25 Jun 2010 16:21:19 GMT (105kb) Title: A systematic description of evaporation spectra for light and heavy compound nuclei Authors: R. J. Charity Categories: nucl-th Comments: 18 pages 21 figures \\ To systematically describe evaporation spectra for light and heavy compound nuclei over a large range of excitation energies, it was necessary to consider three ingredients in the statistical model. Firstly, transmission coefficients or barrier penetration factors for charged-particle emission are typically taken from global fits to elastic-scattering data. However, such transmission coefficients do not reproduce the barrier region of evaporation spectra and reproduction of the data requires a distributions of Coulomb barriers. This is possibly associated with large fluctuations in the compound-nucleus shape or density profile. Secondly for heavy nuclei, an excitation-energy dependent level-density parameter is required to describe the slope of the exponential tails of these spectra. The level-density parameter was reduced at larger temperatures, consistent with the expected fadeout of long-range correlation, but the strong $A$ dependence of this effect is unexpected. Lastly to describe the angular-momentum dependence of the level density in light nuclei at large spins, the macroscopic rotational energy of the nucleus has to be reduced from the values predicted with the Finite-Range Liquid-Drop model. \\ ( http://arxiv.org/abs/1006.5018 , 105kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1006.4899 (*cross-listing*) Date: Fri, 25 Jun 2010 02:14:19 GMT (589kb) Title: CTOF measurements and Monte Carlo analyses of neutron spectra for the backward direction from a lead target irradiated with 200 to 1000 MeV proton Authors: I.

Lu Categories: nucl-ex nucl-th Comments: 23 pages, 12 figures, only pdf, submitted to NIM B Report-no: LANL Report LA-UR-10-04265, Los Alamos (2010) \\ A calorimetric-time-of-flight (CTOF) technique was used for real-time, high-precision measurement of neutron spectrum at an angle of 175 degrees from the initial proton beam direction, which hits a face plane of a cylindrical lead target of 20 cm in diameter and 25 cm thick. A comparison was performed between the neutron spectra predicted by the MARS, RTS&T, MCNP6, and the MCNPX 2.6.0 transport codes and that measured for 200, 400, 600, 800, and 1000 MeV protons \\ ( http://arxiv.org/abs/1006.4899 , 589kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:0806.0747 replaced with revised version Thu, 24 Jun 2010 20:16:38 GMT (941kb) Title: Relativistic mean-field theory applied to the study of neutron star properties Authors: J.P.W.
