Abstract
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.
