S ep 1 99 3 Roles of triaxiality and residual interaction in signature inversions of A ∼ 130 odd - odd nuclei
Rotational bands with (πh 11/2) 1 (νh 11/2) 1 configurations are studied using a particle-rotor model in which a proton and a neutron quasiparticles interacting through a zero-range force are coupled with a triaxial rotor. It is shown for 124 Cs that one can reproduce the signature dependence of energy and B(M1)/B(E2) ratio best when one takes into account γ-deformations with irrotational-flow ...
متن کاملApplication of a semimicroscopic core-particle coupling method to the backbending in odd deformed nuclei.
In two previous papers, the Kerman-Klein-Dönau-Frauendorf (KKDF) model was used to study rotational bands of odd deformed nuclei. Here we describe backbending for odd nuclei using the same model. The backbending in the neighboring even nuclei is described by a phenomenological two band model, and this core is then coupled to a large single-particle space, as in our previous work. The results ob...
متن کاملa swot analysis of the english program of a bilingual school in iran
با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...
15 صفحه اولShapes of neutron - rich A ≈ 190 odd - odd nuclei
Following from the prediction by Hilton and Mang [1] of “giant backbending” in 180Hf, caused by a collective oblate rotational band crossing the prolate ground-state band, there has been further theoretical investigation of this phenomenon [2–5]. The calculated shape change is understood to be induced by the effects of rotation alignment. It is related to the prediction of a ground-state shape ...
