DECAY OF 202Pb* FORMED IN 48Ca+154Sm REACTION USING THE DYNAMICAL CLUSTER-DECAY MODEL

Abstract: The decay of compound nucleus 202 Pb *, formed in entrance channel reaction 48 Ca +154 Sm at different incident energies, is studied by using the dynamical cluster-decay model (DCM) where all decay products are calculated as emissions of preformed clusters through the interaction barriers. The calculated results show an excellent agreement with experimental data for the fusion-evaporation residue cross-section σ ER together with the fusion-fission cross-section σ FF (taken as a sum of the energetically favor… Show more

“…The DCM, for the decay of compound systems, is non-statistical description of dynamical mass motion of preformed clusters through the interaction barrier which treats all types of emissions i.e. evaporation residues (or equivalently light particles LPs (A ≤ 4)), intermediate mass fragments IMFs (5 ≤ A 2 ≤ 20) and fusion-fission ff fragments, on the same footing [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. But the statistical models treat all these emissions on different footing, where these emissions are treated differently on the basis of mass of compound nucleus [28][29][30].…”

“…Some attempts (see, e.g., [2][3][4]) were made to use P CN in determining the evaporation residue cross section σ ER , given as the product of the capture cross section σ capture , the CN formation probaility P CN and the survival probability W sur , each term treated and calculated separately [3]. In this contribution, we introduce for the first time the definition of P CN in to the dynamical clusterdecay model (DCM) of Gupta and collaborators [5][6][7][8][9][10][11][12][13], applied to reactions having non-zero nCN contribution.…”

“…The DCM [9][10][11][12][13][14][15][16][17][18][19][20][21][22], an adaptation of the preformed-cluster model for ground-state decays [27][28][29], is based on dynamical (or quantum-mechanical) fragmentation theory. It is worked out in terms of the collective coordinates of mass and charge asymmetries…”
