Energy dependence of inelastic proton scattering to the 3&#175;, 2.614 MeV state in <SUP>208</SUP>Pb

The recent work of McDaniels et al. regarding the inelastic excitation of the 3&#175; state at 2.614 MeV in 208Pb by protons with energies between 100 and 800 MeV has been expanded with the inclusion of the data at other proton energies down to -35 MeV. It is found that the deformation length, &#948;, for this state, extracted using the collective distorted-wave Born approximation formalism, remains nearly the same in the energy region between 35 and 800 MeV. Combining the &#948; values determined from the (p,p') measurements with those obtained from the electromagnetic methods, the ratio of the neutron and proton transition matrix elements (Mn/Mp) has been determined for this state
