In the present work, an attempt has been made to explain the recent cosmic
acceleration with two mutually interacting scalar fields, one being the
Brans-Dicke scalar field and the other a quintessence scalar field. Conditions
have been derived for which the quintessence scalar field has an early
oscillation and it grows during a later time to govern the dynamics of the
universe.Comment: 8 pages, no figures. Accepted for publication in Mod. Phys. Lett.
