Abstract
Estimates for a weaker isovector potential than previously adopted are put forward. It is also strongly mass and, energy dependent. The resu lting isovector particle-hole interaction is weaker in Lighter nuclei and the isovector quadrupole resonance should be located at lower ener gy than previously expected. The uncertainties arising from the separa tion of the potential asymmetry energy in nuclear matter calculations are discussed.
