Low-energy (E/sub v/10, spin- (if any) and isospin-dependent effects are comfortably below 10% of the coherent scattering. In the case of the neutron, the cross-section for momentum transfer, when compared to that of the isoscalar current, is: i) more than one order of magnitude larger in model I; ii) about twice larger in model II. It is noted that the vector model gives more dramatic effects in the supernova 'strategy' both lowering the cross-section in the inner core and increasing it in the outer region. (16 refs). |
