Influence of incomplete fusion on complete fusion: Observation of a large incomplete fusion fraction atE≈5−7MeV/nucleon

Influence of a one-neutron-excess projectile on low-energy incomplete fusion

“…Thus, a comparison of experimental EFs with the statistical model code PACE4 may indicate the extent to which the formation of identified ERs may be explained by the equilibrated CN decay. Any deviation in the experimental EFs with respect to the PACE4 predictions may be attributed to ICF, which is not included in this code [44][45][46][47][48]. channels.…”

“…Due to the unavailability of any reliable theoretical model to explain low-energy ICF data, the study of ICF is still an active area of investigations. Further, the observation of ICF at slightly above barrier energies where CF is supposed to be the sole contributor has triggered the study of low-energy ICF [3,44,45,53,54].…”

“…In order to study low-energy ICF, several inclusive experiments have been performed at the Inter-University Accelerator Center (IUAC), New Delhi [44][45][46][47][48]. This work is an extension of our earlier measurements to study the effect of a one-neutron (1n) excess projectile on the onset and strength of ICF.…”

“…The aforementioned models have been used to fit the experimental data obtained at energies well above the Coulomb barrier (i.e., E lab 10.5 MeV/nucleon) but have shown certain failings in their ability to explain ICF data at relatively low bombarding energies (i.e., ≈ 3-7 MeV/nucleon) [44][45][46][47][48][49][50][51]. More recently, Diaz-Torres et al [52] proposed a three-dimensional classical model for low-energy breakup fusion reactions.…”

“…In addition to the fission and quasifission [7][8][9][10][11][12], the existence of incomplete fusion (ICF) [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] at low incident energies (i.e., ≈ 4-7 MeV/nucleon) may add complexity to the synthesis of superheavy elements. In general, at these energies, CF is supposed to be the sole contributor to the total fusion cross section [26,27].…”
