Query: Momentum distributions, spin-dependent observables, and the D_2
  parameter for 3He breakup   Using a recent parametrization of the fully antisymmetric three-nucleon wave
function, based on the Paris and CD-Bonn potentials, we analyze the momentum
distributions of constituents in 3He, as well as the spin-dependent observables
for (3He,d) and (3He,p) breakup reactions. Special attention is paid to the
region of small relative momenta of the 3He constituents, where the single
parameter, D_2, has determining role for the spin-dependent observables in the
d+p channel. This fact results in some useful relations between experimental
observables.
