Electromagnetic form factors in the deuteron
Adler has calculated a correction to the deuteron's impulse electromagnetic form factors by introducing meson exchange current effects. He approximated the corrections to the charge and quadrupole form factors by neglecting the contribution arising from the "w2" type terms. A mathematical expression for the deuteron's impulse electromagnetic form factors is obtained. Meson exchange currents are then taken into consideration and these give rise to an exchange current. Here the form factors arising from meson exchange currents and charge distributions that include the effect due to the "w2" type terms are calculated. These form factors are taken to be their corrections to the impulse form factors. It was found by Adler that the corrections mentioned above may resolve the long standing discrepancy between experiment and theory on the static magnetic moment of the deuteron. At higher momentum transfers, however, a deviation between the Adler-Drell theory and experiment has been observed. Finally, suggestions are made for calculations that may result in agreement between theory and experiments, even at high momentum transfers.
