On the Role of Initial Conditions in Background Suppression for Fusion-Evaporation Reactions / D.A.Ibadullayev, Yu.S.Tsyganov, A.N.Polyakov, M.V.Shumeiko, A.A.Voinov. – Text : electronic // Advances in Nuclear Science and Applications. – 2026. – Vol. 2, No. 2. – P. 94-103. – URL: https://doi.org/10.63907/ansa.v2i2.86. – Bibliogr.: 20.

A new approach is presented for optimizing the application of the active correlations method for substantial background suppression in experiments aimed at detecting rare alpha-decay and spontaneous-fission events in complete-fusion nuclear reactions. The proposed optimization steps concern parameters such as the minimum energy of signals attributed to nuclei implanted into a silicon DSSD detector, the time-correlation interval, and the relative loss of target irradiation time. A test using a silicon n-Si(Au) detector and a special ICS-119 unit is described. The amplitude spectrum of registered signals for a nucleus with is calculated for the DGFRS-2 setup at FLNR JINR using an additional thin aluminum absorber to reduce the background from short-range heavy particles. It is assumed that these parameters will be used in the upcoming experiment *2*4*9Ил+*5*0Ti *> 119* in the near future. The background load is estimated on the basis of the experiment *2*4*2Pu+*5*0Ti *> Lv* . In this context, the present work can be considered a continuation of several previous studies devoted to the detection system and to the improvement of the ''active'' correlations method in complete-fusion reactions with heavy ions.
