Abstract：
Based on variational method,we systematically studied the dynamical structures of A≤4 S shell Λ hypernuclei with the aid of the harmonic oscillator product expansions and the generalized Talmi-Moshinsiky transformation.We also made investigations on structures of the osdinary nuclei for A=2 and 3. By comparis on,we can see that the root mean distances between nucleons are shorten due to the presence Λ hyperon which compresses the core. Λ hyperon acts as the adhesive. The studies on internal structures of nuclear system show that the relative motions between particles are mainly in 0s orbits.
