We have performed a relativistic treatment at low energy of
electron–argon scattering which includes both polarisation and dynamic
distortion effects. Our results are in excellent agreement with the
experimentally derived momentum transfer cross section and scattering length,
as well as with very recent measurements of the elastic differential cross
section.
We have investigated the form factors of the π and K mesons within the framework of the statistical model. Our results reveal several well-spaced minima and maxima for different values of Q2, the square of the momentum transfer. The characteristic features of the elastic differential cross section, dσ/dt, for π±P and K±P scattering data are well reproduced, as a consequence.
