A Theoretical Study of Atom-Molecule Ramsay Fringes of Bose-Einstein Condensation and Evaluation of Its Parameter as a Function of Magnetic Field

L. P. Mishra and L. K. Mishra

In this paper, we have theoretically studied the physical properties of atom-molecule Ramsay fringes of Bose-Einstein Condensate of 85Rb atom in hyperfine state. Using the theoretical formalism of Goral et al.9 , we have evaluated the natural frequency, two-body loss rate constant K2 and visibility of Ramsy fringes as a function of magnetic field strength Bevolve (G). Our theoretically evaluated results are in satisfactorily agreement with the experimental data.
