The reaction 56Fe(p, n)56Co leading to the analog of the ground state and the first excited 2+ state of 56Fe has been studied at Ep=20, 28, 32 and35MeV. The direct process dominates at higher energies, thus the direct extraction of the isovector deformation parameter β(1)2 is feasible. It is found that β(1)2 is about three times larger than β(0)2, the isoscalar deformation parameter.
