PC -based code for simulations heavy ion induced nuclear reaction products implanted into silicon detector, and one for recoil passing through the separator and TOF detection gaseous pentane-filled low pressure module of the Dubna Gas-Filed Recoil Separator are presented[1-3]. Additionaly, code simulating spontaneous fission of reaction product is presented too. The value of average pulse height defect (PHD) is used as an one free parameter of calculation. It can be easily obtained (and, respectively fixed) from the test 206Pb+48Ca->252No+2n nuclear reaction. No attempts were done to present the recombination and stopping components of PHD separately, as well as angullar dependence of the residual defect due to relatively high resistivity of the silicon detector operating under low electric field condition. Description of TOF-E detecting module (and associated systems) is presented in brief.
