J. Carbonell et Va. Karmanov, RELATIVISTIC WAVE-FUNCTION OF THE NP SYSTEM IN THE J(PI)=O-SPECTRUM STATE( CONTINUOUS), Nuclear physics. A, 589(4), 1995, pp. 713-723
The relativistic light-front wave function for the nonrelativistic cou
nterpart of the np S-1(0) scattering state is calculated in the one-bo
son-exchange model. This wave function is determined by two components
instead of one in the nonrelativistic case. The extra component havin
g a relativistic origin is found to dominate at q greater than or equa
l to 400 MeV/c.
