“…We have noticed that the effect of α c is not strong for 4n-structured (even and α) fragments compared to other fragments. The results obtained in our earlier work [15], and the results presented in figure 1, clearly shows that, a larger value of α c requires a smaller value of △R and vice-versa. A larger value of α c means that, the radius of the cylinder assumed in the hydrodynamical model, will be larger and hence the flow of nucleons will be requiring smaller neck i.e., smaller △R.…”

“…In DCMʼs earlier calculations [12,14], α c = 0.4 is used. Earlier, we have studied [15] the role of α c (varied from 0.4 to 0.8) for the decay of Cu 59 . The factor α c appearing in equation ( 5) has a significant effect on the calculation of preformation probabilities (P 0 ) and it is studied for the binary fragmentation of nuclei in different mass regions [20].…”

“…In [14], we have taken a different neck length parameter values for LPs and IMFs, our obtained results are comparable with the experimental data only for α-structured nuclei but not for all the fragments.

The reformulated dynamical cluster-decay model (DCM) is applied to study the role of the neck-length parameter for the decay of even-A and α-structured * Ni 56 formed in the + S Mg 32 24 reaction at = E 60.5 MeV c m . . . Experimentally, light particles (LPs, ⩽ A 4) emission cross-section and individual fragments (from A = 12 to 28) emission cross-section are measured for this reaction at = E 60.5 MeV c.m.. In the present work, we have reproduced the measured data of LPs emission cross-section and mass spectra of A = 12-28 fragments by varying the neck-length parameter △R and the factor α c , which is present in the hydrodynamical mass calculation. From the fitted △R values, polynomial relations are obtained for 4n-structured (even and α-fragments, A = 12, 16, 20, 24 and 28), 4n+1-structured odd mass fragments (A = 13, 17, 21, and 25), 4n +2-structured (even and non-α fragments, A = 14, 18, 22, and 26) and 4n+3structured odd mass fragments (A = 15, 19, 23 and 27). Experimentally, there is no data for fragments A = 5-11 emission cross-section. In order to account for the cross-section information about these fragments, we have extrapolated the △R values for these fragments with the use of fitted polynomial relations. To fit the calculated LPs emission cross section with the measured data, we kept △R values of fragments A = 5-28 and tuned the △R value of LPs alone. The fitted △R value of LPs is as 1.3146 fm. With the use of fitted △R values of fragments A = 1-4 and A = 12-28 and extrapolated △R values of fragments A = 5-11, our calculated overall cross-section values of the LPs emission and individual fragments (A = 12-28) emission cross-section are found to be in better agreement with the experimental data.
