The reviewer pointed out that the validity of the calculation results was not enough so I added the verification experiment in response to his questions How should I answer his questions

When addressing the reviewer's concerns about the validity of the calculation results, you can explain the steps you took to improve the accuracy of your findings. You can also provide details about the verification experiment you conducted, including the methodology, data analysis, and results. Here is an example response:

Dear Reviewer,

Thank you for your feedback and for raising concerns about the validity of our calculation results. We appreciate your valuable comments and have taken them into consideration when revising our manuscript.

To address your concerns, we conducted a verification experiment to validate the accuracy of our findings. The experiment involved replicating the same calculations using a different methodology and comparing the results. We used a different software package and input parameters to avoid any potential biases or errors.

The results of the verification experiment were consistent with our original findings, indicating that our calculations were accurate and reliable. We have included the details of the verification experiment in the revised manuscript, including the methodology, data analysis, and results.

We hope that this additional information will address your concerns and provide further support for the validity of our calculation results. Thank you again for your valuable feedback.

Sincerely, [Your Name]
