In fast ignition (FI) mechanism, a pellet containing the thermonuclear fuel is first compressed by a nanosecond laser pulse, and then irradiated by an intense "ignition" beam, initiated by a high power picosecond laser pulse, is one of the promising approaches to the realization of the inertial confinement fusion (ICF). If the ignition beam is composed of deuterons, an additional energy is delivered to the target, in which coming from fusion reactions of the beam-target type, directly initiated by particles from the ignition beam .In this article, the D+T fuel is selected and at first step we compute new average reactivity using three parameter cross section formula in terms of temperature at second step we use the obtained results of step one and calculate the total deposited energy of deuteron beam inside the target fuel at available physical conditions, then in third step we write the nonlinear point kinetic balance equation of D+T mixture and solve numerically these nonlinear differential coupled equations versus time .In forth step ,we estimate the power density and energy gain under physical optimum conditions and finally we conclude that maximum energy deposited in the target from D+T and D+D reaction are equal to 19269.39061 keV and 39198.58043 keV, respectively
