In isobaric models for inertial confinement fusion it is assumed that the target configuration at stagnation time (maximum compression) consists of two regions, hot spark and cold fuel, respectively. Here the conditions of spark formation and ignition in hydrogen equimolar isotopes in central spark ignition are investigated and permissible values of H, and Is are evaluated numerically. By introducing a dimensionless parameter, יtis, the class of targets are considered by the specific value of יVs. Finally, limiting fuel energy gain curve (Gf *) as a function of ignition energy (Ejgn) allows different implosion velocities to be calculated. This result is in good agreement with more complex hydrodynamic models
