We study the Schwinger effect in a system of nonparallel D1-branes for the bosonic
strings using the path integral formalism. We drive the string pair creation rate by
calculating the one-loop vacuum amplitude of the setup in presence of the background
electric field defined along one of the D1-branes. We find an angle dependent minimum
value for the background field and show that the decaying of vacuum into string pairs
takes place for the field above this value. It is shown that in
limit the vacuum
becomes stable and thus no pair creation occurs.
