Addendum to 'The quasi-deuteron model for the trinucleon'

Abstract

Trinucleon form factors are analysed using Schiff's 1964 formalism, for a combination of completely symmetric S and mixed symmetry S' states. The electric isoscalar form factor depends only on the Fourier transform of the S-state wavefunction; but the magnetic isoscalar form factor also involves the Fourier transform of the product of S and S' wavefunctions. Therefore the authors earlier treatment of the magnetic isoscalar form factor to find the number of quasi-deuterons was not correct. They use the electric isovector form factor and nucleon form factors to provide a criterion to support Saclay results on the magnetic isoscalar form factor instead of the Bates measurements.
