Clusters in Light, Heavy, Super-Heavy and Super-Superheavy Nuclei

Abstract: Clustering phenomenon in nuclei is studied within the relativistic as well as non-relativistic mean field approaches, and also as a collective clusterization process in the decaying hot compound nucleus.

“…the entrance channel center of mass (c.m.) energy and max the maximum angular momentum whose value depends on the choice of moment-of-inertia I in the sticking (I = I S ) or nonsticking (I = I NS ) limit for the angular-momentum-dependent potential (see [16,18,21], and also below). m is the nucleon mass.…”

“…For this purpose, we choose to calculate the fusion evaporation residue cross sections σ ER for the three cases of Z = 114, 120 or 126 and N = 184 as magic numbers, using the hot fusion reaction 48 Ca+ 238 U→ 286 112 * as an example. We use the dynamical cluster-decay model (DCM) of Gupta and Collaborators [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] for calculating σ ER , where the shell corrections for the three cases of Z = 114, 120 or 126, N = 184 are calculated from the 'empirical' formula of Myers and Swiatecki [5]. Of course, the liquid drop energies have also to be modified accordingly, taken from the work of Davidson et al [24], based on Seeger's mass formula [25].…”

“…For a compound nucleus reaction, the fusion cross-section σ fus is defined as the sum of the cross-section due to the emission of light particles (LPs), the so-called evaporation residue or fusion-evaporation cross-section σ evr , and the fission cross-section due to the decay of compound nucleus into symmetric and/or near symmetric fragments, the so-called fusionfission (ff) component σ ff . For a medium mass compound system, such as 116 Ba * formed in the 58 Ni+ 58 Ni reaction [4,5], instead of the complete ff cross-section [6,7], fragments or 'clusters' of intermediate masses, denoted σ IMF , are observed at both the high and medium, abovebarrier energies. More recently, however, the ff component is measured for the neighbouring 118,122 Ba * isotopes formed in 78,82 Kr+ 40 Ca reactions at further lower energies [8].…”

“…and the nuclear proximity potential for deformed, oriented nuclei employing temperature effects, reads as V P (s 0 (T )) = 4π R(T )γb(T )Φ(s 0 (T )) , (5) where b(T ) is the nuclear surface thickness, γ is the surface energy constant, R(T ) is the mean curvature radius and Φ(s 0 (T )) is the universal function (for more details see Refs. [33][34]). The angular momentum effects are included via the following expression…”
