演題:IS and IV pairing correlations and Spin-Isospin Response
場所:ウェスト1号館7階 物理会議室 (W1-A-723室)
概要:
Pairing correlations are one of the most important effects in nuclear structure and reactions.Spin-singlet isovector pairing correlations have been discussed from late 1950s and the spin-singlet superfluidity is well established in several observations such as the energy spectra of even-even nuclei and the moment of inertia of deformed nuclei. It is also known that the spin-triplet isoscalar pairing interaction is much stronger than the isovector one in the nuclear matter calculations. The existence of deuteron certainly proves the strong spin-triplet isoscalar correlations. I will discuss in this talk how we can nd out the effect of isoscalar pairing correlations in spin-isospin response of N=Z nuclei, especially magnetic dipole transitions and Gamow-Teller transitions.
