Mean-field calculations with the Gogny force including the Tensor force Daisuke ABE Department of Physics, University of Tokyo JSPS Research Fellow and Takaharu OTSUKA Center for Nuclear Study RIKEN August 2nd 2006 KEK

Motivation To understand exotic phenomena appearing in unstable nuclei To investigate, in particular, Tensor-force effect on single-particle energies (SPE) because its effect on them is quite different from that of the LS force August 2nd 2006 KEK

Brief description of the Tensor Force originates from the p- (and r-) meson exchange. plays an important role in nuclear properties, such as binding energies. can influence on SPE in the different way compared to the LS force. August 2nd 2006 KEK
