title = "Reduction of magnetic and transverse electric scattering amplitudes in 207Pb by core polarization",
abstract = "It is shown that core-polarization causes a considerable reduction of the nuclear magnetization current at high momentum transfer irrespective of multipolarity. The reduction is consistent with the observed reduction of both magnetic and transverse electric form factors in the 207Pb and 208Pb nuclei. No corresponding systematic reduction is expected in the nuclear convention current.",

note = "Funding Information: In recent high resolution electron scattering experiments on 207pb \[1,2\]t he low lying neutron hole excitations have been studied. It has been observed that there is a systematic reduction of the transverse scattering amplitude to about 55% of the single particle value, independent of the transition multipolarity and the momentum transfer investigated. Various mechanisms were suggested to explain this reduction. In this letter we present a calculation of the core polarization effect on the nuclear magnetization currents which accounts for a substantial part of this reduction in both magnetic and electric transitions. We use the same model \[3\]b y which a similar reduction was obtained in the high spin transitions (j~r = 12-, 14-)in 2°8pb \[4\].W hile in the latter only the first maxima of the magnetic form factors have been measured those of 1 Supported in part by U.S.D.O.E. contract No. DE-AC0276 ER03069. 2 Address after Sept. 1980: Nordita, Blegdamsvej 17, Copen-hagen, Denmark. 3 Address after Sept. 1980: Tel-Aviv University, Tel-Aviv, Israel. 4 Supported in part by the National Science Foundation.",
