چکیده
در این مقاله به بررسی گذار فاز کوانتومی (QPT) زنجیره‌ی ایزوتوپی زنون (Xe132-122) در چارچوب مدل‌های اندرکنش بوزونی1 و بوزون-فرمیونی1 پرداخته شده است. ما برای مطالعه‌‎ی QPT در این زنجیره از مشاهده‌پذیرهایی مانند: انرژی بستگی، انرژی جداسازی دو نوترونی، انرژی واپاشی آلفازا، 2/4R و (2B(E استفاده کردیم. نتایج حاصل از محاسبات نشان داد که هسته‌های گذار در ناحیه‌های برای ایزوتوپ­‌های زوج - زوج و  برای ایزوتوپ‌های زوج - فرد به ترتیب Xe130 و Xe127 می‌باشند.

چکیده English

In this paper, Quantum Phase Transition (QPT) for the Xenon (122-132Xe) isotopes chain in the frameworks of the IBM-1 and IBFM-1 is considered. In order to study the QPT in this chain, we have used the observables such as: binding energy, two neutron separation energy, Alpha decay energy, R4/2 and B(E2). The results show that transitional nuclei in the regions of  for even-even isotopes and  for even-odd isotopes are 130Xe and 127Xe respectively.
