  From the quark confinement idea, we conjecture that the quarks compose
colorless particles (uud and udd - the Lee Particles) and then the Lee
Particles construct a body center cubic lattice in the vacuum. In terms of the
energy band theory, from the symmetries of the body center cubic periodic
field, we deduce the baryon spectrum (with a united mass formula) using only 2
flavored quarks u and d. We also predict some new baryons: $\Lambda^{0}$(2559),
$\Lambda_{C}^{+}$(6659), $\Lambda_{b}^{0}$(10159).... The experiments to find
the long lifetime baryon $\Lambda^{0}$(2559) should be done first.
