“…In the eighties and nineties, a number of light heavy-ions (such as 12 C, 16 O, 20 Ne etc.) induced reactions on heavy nuclei was performed to investigate CF-ICF using particle-gamma coincidence techniques and recoil range distribution techniques [11][12][13][14][15][20][21][22][23]. It is observed that the articles [18][19][20][21] are consistent with the sum rule model [24] and [13][14][15]23] with the breakup fusion model [25] [18,19,[26][27][28].…”

“…Another possibility is the sequential merging of the fragments into the target which could not be experimentally distinguished from the CF process. Experimentally, one can usually measure total fusion (CF + ICF) cross-section, except some special cases, for instance, a heavy mass nuclei where neutron emission (apart from fission) is only dominant channel and emission of charge particles are usually hindered due to large Coulomb barrier [11]. For the weakly bound projectiles having low breakup thresholds, fusion-like processes can be influenced either by static effects as the shape of the target-projectile potential may affected by large diffuseness in density 3 distribution or by dynamical effects due to coupling to bound states as well as to the continuum.…”

Li7 -induced reaction on Monat : A study of complete versus incomplete fusion

Background: Several investigations on the complete-incomplete fusion (CF-ICF) dynamics of α-cluster well-bound nuclei has been contemplated above the Coulomb barrier (∼ 4-7 MeV/nucleon) in recent years. It is therefore expected to observe significant ICF over CF in the reactions induced by a weakly bound α-cluster nucleus at slightly above the barrier.Purpose: Study of the CF-ICF dynamics by measuring the populated residues in the weakly bound 7 Li+ nat Mo system at energies slightly above the Coulomb barrier to well above it.Method: In order to investigate CF-ICF in the loosely bound system, 7 Li beam was bombarded on the nat Mo foils, separated by the aluminium (Al) catcher foils alternatively, within ∼ 3-6.5MeV/nucleon. Evaporation residues produced in each foil were identified by the off-line γ-ray spectrometry. Measured cross section data of the residues were compared with the theoretical model calculations based on the equilibrium (EQ) and preequilibrium (PEQ) reaction mechanisms. Results:The experimental cross section of 101m,100,99m,97 Rh, 97,95 Ru, 99m,96,95,94,93m+g Tc and 93m Mo residues measured at various projectile energies were satisfactorily reproduced by the simplified coupled channel approach in comparison to single barrier penetration model calculation.Significant cross section enhancement in the α-emitting channels was observed compared to EQ and PEQ model calculations throughout observed energy region. The ICF process over CF was analyzed by comparing with EMPIRE. The increment of the incomplete fusion fraction was observed with increasing projectile energies. Conclusions:Theoretical model calculations reveal that compound reaction mechanism is the major contributor to the production of residues in 7 Li+ nat Mo reaction. Theoretical evaluations substantiate the contribution of ICF over the CF in α-emitting channels. EMPIRE estimations shed light on its predictive capability of cross sections of the residues from the heavy-ion induced reactions.

“…While at lower beam energies CF is the dominating process, ICF emerges as a competing process, generally at high energies. Early experiments to study ICF reaction mechanism were confined to high beam energies of  10 MeV/A [1] but recently there have been reports for ICF competing with CF even at beam energies as low as 5 MeV/A [2][3][4]. Many models have been proposed to explain the underlying reaction mechanism of ICF reactions.…”

Abstract. The excitation functions of the evaporation residues, produced via complete fusion and incomplete fusion reactions of 11 B + 122 Sn, were measured for the projectile energy of around 6 MeV/A by the off-line gamma spectrometry. The cross sections have been compared with the statistical model code Projected Angular Momentum Coupled Evaporation (PACE4). The original sum rule model underestimated the ICF cross sections. We therefore made modification in the model mainly to incorporate the energy dependence in the definition of critical angular momentum. Using this modified sum rule model, we found a significant improvement in the results.

“…The calculations of Wilsczynski et al [6] for the cross section for ICF fractions in the reaction 14N § show that ICF becomes significant only for energies above 10 MeV/amu. On the other hand some recent studies [7][8][9] on lighter targets (A < 100) have shown that ICF occurs even at much lower projectile energies (5 MeV/amu). The mechanism of such ICF at low projectile energies is still not very clear.…”

Excitation functions for the evaporation residues for the reactions 12C + 93Nb and 160 + 89y in the projectile energy range Of 4 to 6.5 MeV/amu have been measured using off-line gamma spectrometry. The excitation functions for neutron(xn), proton(pxn) and one alpha(exn) emission channels are practically similar for both the reactions. However the products formed by two alpha(2exn) emission show much higher cross sections in the 12C-[-93Nb than the 160-[-s9y system. This has been explained in terms of the incomplete fusion process involving transfer of an alpha particle from the projectile to the target in the former case.
