摘要：
We investigate the electric dipole (E 1) resonance states of Lambda hyper-nucleus using a time-dependent mean-field model. The model is the canonical-basis time-dependent Hartree-Fock-Bogoliubov theory (Cb-TDHFB) with Skyrme-type effective interaction and smoothed constant pairing interaction. The linear response calculation with Cb-TDHFB is performed in the three-dimensional Cartesian co-ordinate space to treat deformed nuclei. We report the E1 strength functions of carbon isotopes and discuss the influences of a Lambda particle on the ground states and the excited states of the hypernuclei.
