SEARCHING FOR EFFECTS OF TENSOR FORCES IN NUCLEI

Effects of tensor interactions in nucleus are discussed from the experimental view points. Two recent studies, one is the mixing of s- and p-waves in (11)Li halo and the other is the high momentum component in the nucleon wave function from a transfer reaction. Preliminary results of (16)O(p,d)(15)O reaction show an abnormal relative enhancement of the transition to the positive parity state of (15)O, which is not a hole state, consistent with contents of high momentum nucleon expected from the tensor interactions. The importance of the inclusion of tensor force, that can not be described in the mean field model, is discussed.
