In this research, the basic equation which describe the evaluation of
population and phase during the time for Boson-Josephson Junction has
been concluded in to consider two and three body interaction potential.
Then josephson frequencies have been calculated of BJJ in the presence
of three body interaction.
In this researchthe Gross - Pitaevskii equationhas been concluded taking in to consideration
tow and three body interaction potential. The results were compared to
thesta-te in which the twobody interaction has been accepted. Thenelementary
excitementfrequencies have been calculated of Bose Einstein condensation in the presence
of three body interaction.
