Research Abstract |
First we have established a method of calculating response functions involving continuum states, by testing it in ab initio study of photoabsorption cross section of 4He. Good agreement with experiment, obtained with a realistic nuclear interaction, has made it possible to extend the method to the Gamow-Teller and spin-dipole response functions of 4He that are relevant to neutorino-4He reaction.
