التحليل البنيوي لنظائر التنجستن (_74^(168-172))W الشفعية- الشفعية باستخدام نموذج البوزونات المتفاعلة IBM-2

الملخص

In this study the energy levels (y-rast) have been calculated by using the interacting boson model (IBM-2), for the even-even tangesten ^168-172w isotopes and the results compared with the experimental data, and they were a good match. The dynamic symmetries were able to determine after these calculations, by used several tests like ratio , , and E-GOS. The results were compared with availalable limits, rotation SU(3),soft-Gamma O(6) and vibration U(5),X(5) and E(5) for each isotope. The even-even 168-172W isotopes are going on from rotational SU(3) which passing by  – soft (unstable) O(6) which are X(5) limits
