چکیده
بررسی ساختار هسته با در نظر گرفتن خاصیت زوجیت بین نوکلئون‌ها، نقش مهم و تأثیرگذاری در محاسبه کمیت‌های ترمودینامیکی هسته دارد. در این کار با استفاده از مدل BCS و در نظر گرفتن خاصیت زوجیت، خواص ترمودینامیکی هسته مطالعه شده است. نماینده زوجیت در این مدل، پارامتر گاف می‌باشد. با محاسبه پارامتر گاف در دماهای مختلف، انرژی برانگیختگی، پارامتر چگالی‌تراز وابسته به دما و چگالی‌تراز هسته‌ای با استفاده از مدل BCS به دست آمده است. در ادامه با استفاده از پارامتر چگالی‌تراز وابسته به دما، چگالی‌تراز هسته‌ای براساس مدل BSFG حساب شده است. در انتها، نتایج چگالی‌تراز هسته‌ای محاسبه شده با استفاده از روش‌های مذکور، با یکدیگر و سپس با داده‌های تجربی مقایسه شده است.

چکیده English

Studying the structure of the nucleus through the consideration of pairing correlation between nucleons plays a crucial role in determining the thermodynamic properties of the nucleus. In this study, we examined the thermodynamic characteristics of the nucleus using the BCS model, which incorporates pairing correlation. The gap parameter serves as the symbol of pairing correlation in this model. By calculating the gap parameter at various temperatures using the BCS model, we were able to determine the excitation energy, temperature-dependent level density parameter, and nuclear level density. Additionally, we calculated the nuclear level density using the BSFG model and the temperature-dependent level density parameter. Finally, we compared the results of the nuclear level density obtained through these methods with each other and experimental data.
