Towards Understanding Incomplete Fusion Reactions at Low Beam Energies: Modified Sum Rule Model

Round 1

Reviewer 1 Report

The authors studied experimentally and theoretically the cross sections for complete and incomplete fusion in the reactions 10,11B+124Sn and 11B+122Sn at bombarding energies 5-8 MeV/nucleon. They suggested the modified sum rule model reproduce their experimental data. The main difference between their model and the well-known old sum rule model is the redefinition of the critical angular momentum of the reaction by introducing its dependence on the beam energy.

1. The main question addressed by the research is the competition between
between complete and incomplete fusion at low incident energies.

2. The topic is relevant in the field. It addresses a specific gap in the field.

3. It adds to the subject area new experimental results for the specific reactions. The authors modified the original sum rule model and gave the theoretical explanation for their experimental data.

4. I do not see any specific improvements should the authors consider
regarding the methodology. Due to the short lifetimes and stable parent
nuclei some exit channels were not observed.

5. The conclusions are consistent with the evidence and arguments presented. They address the main question posed.

6. The references are appropriate.

7. I have no additional comments on the tables and figures.

I think that this article will be interesting for the nuclear community.

Reviewer 2 Report

The manuscript is well written with sufficiently improved theoretical analysis of the results obtained by modifying the SUMRULE Model.

-The mechanism of nuclear reactions based on impact factor and its theoretical explanation ha been worked upon for past few decades. This is evident from the large number of models being proposed to explain the observed cross sections of PEQ, transfer and ICF reactions. In this manuscript, the authors present the CF and ICF data measured in 10B and 11B induced reactions on 122Sn and 124Sn. For comparing the experimental data, the most widely used SUMRULE MODEL by Wilczynski et al. is modified to take into consideration the energy dependence in the definition of critical angular momentum.

-The topic is relevant and is an area of continued research. The initially proposed models are being constantly modified so as to explain the experimentally observed data. The authors have modified the SUMRULE model in a different aspect, considering a significant overlap, thereby having contribution to ICF from non-peripheral collisions.

-The results are in line with the other published material. It is another line of approach to the subject area compared with other published material

-The approach and methodology looks fine.

-The conclusions are consistent with the evidence and arguments. The authors have tried to answer the main question posed. As evident from their discussions, the model has further scope of modification as well if better experimental data are made available.

-The references are appropriate.

A few typographical mistakes were observed. authors may read the text carefully and rectify appropriately.
