Rohozinski, J. Dobaczewski, W. Nazarewicz Categories: nucl-th Comments: 26 RevTex pages, 1 eps figure, 9 tables, submitted to Physical Review C \\ Symmetry properties of densities and mean fields appearing in the nuclear Density Functional Theory with pairing are studied. We consider energy functionals that depend only on local densities and their derivatives. The most important self-consistent symmetries are discussed: spherical, axial, space-inversion, and mirror symmetries. In each case, the consequences of breaking or conserving the time-reversal and/or proton-neutron symmetries are discussed and summarized in a tabulated form, useful in practical applications. \\ ( http://arxiv.org/abs/0910.5270 , 82kb) ------------------------------------------------------------------------------ \\ arXiv:0910.5277 Date: Wed, 28 Oct 2009 02:08:42 GMT (1011kb) Title: Effect of Tensor Correlations on Single-particle and Collective States Authors: H. Sagawa Categories: nucl-th Comments: 12pages, 5figures, proceedings of international conference on NSRT (Nuclear Structure and related topics), June 2009, Dubna, Russia \\ We study the effect of tensor correlations on single-particle and collective states within Skyrme Hartree-Fock and RPA model. Firstly, We study the role of tensor interactions in Skyrme effective interaction on the spin-orbit splittings of N=82 isotones and Z=50 isotope. The isospin dependence of the shell structure is well described as the results of the tensor interactions without destroying good properties of the binding energy and the rms charge radii of the heavy nuclei. Secondly, We performed self-consistent HF+RPA calculations for charge exchange 1$^+$ states in $^{90}$Zr and $^{208}$Pb to elucidate the role of tensor interactions on spin dependent excitations. It is pointed out that Gamow-Teller(GT) states can couple strongly with the spin-quadrupole (SQ) 1$^+$ states in the high energy region above E$_x$=30 MeV due to the tensor interactions. As the result of this coupling, more than 10% of the GT strength is shifted to the energy region above 30 MeV, and the main GT peak is moved 2 MeV downward. \\ ( http://arxiv.org/abs/0910.5277 , 1011kb) ------------------------------------------------------------------------------ \\ arXiv:0910.5385 Date: Wed, 28 Oct 2009 14:31:09 GMT (76kb) Title: The nucleon recoil effect in antikaon-deuteron scattering at threshold Authors: V. Baru, E. Epelbaum, A. Rusetsky Categories: nucl-th Comments: 7 pages, 3 figures, Proceedings of the International Workshop on Effective Field Theories, 1st - 6th February 2009, PoS(EFT09)028 \\ We investigate the role of the nucleon recoil for antikaon-deuteron scattering using EFT. In particular, we show that the leading correction to the static term that appears at order $\xi^{1/2}$ (where $\xi=m_K/M_N$) cancels completely in the double scattering process. We calculate the higher order recoil corrections and study the pattern of convergence of the expansion method. We find that the recoil correction to the double scattering process is of order of 10-15% of the static contribution. \\ ( http://arxiv.org/abs/0910.5385 , 76kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:0907.3911 replaced with revised version Wed, 28 Oct 2009 12:53:56 GMT (62kb) Title: p-Wave pion production from nucleon-nucleon collisions Authors: V.
