Abstract
Restriction on the neutron-antineutron oscillation time in vacuum
is obtained from latest SNO-data on the deuteron stability,
τD>3.01•1031 years. Calculation performed within the quantum
field theory based diagram technique reproduces satisfactorily results of the
potential approach previously developed. The dependence of the obtained
restriction on the total spin structure
of the annihilating -system and the
deuteron wave function modifications is discussed.
