Abstract The excitation functions of proton induced nuclear reactions on nat Te were measured using the stacked-foil technique up to 14.5 MeV. Samples thin uniform layers Ti-backing prepared by electro-deposition. Nuclear reaction cross sections for formation 120g,121,123,124,125,126,128,130(m+g) I determined and their theoretical thick target yields calculated. obtained data compared with previously published experimental results values theoretically ALICE-IPPE computer code.
A two-parameter nuclear softness (NS2) model for the transition energies is proposed by treating variation of moment inertia with spin. The has been applied to yrast superdeformed (SD) bands in even-even nuclei mass region $\sim $ 190. parameters have determined from fitting procedure order minimize relative root mean square deviation between experimental E2 $\gamma $-ray and calculated ones. basic data on SD are given form a series transitional spins were our previous works. excellent...
The sd-version of the interacting boson model (IBM) is used to establish shape phase transitional structure. A simplified Hamiltonian which intermediate between three dynamical symmetries U(6), namely spherical U(5), prolate and oblate deformed SU(3) $$\gamma $$ -unstable O(6) limits. potential energy surfaces (PESs) IBM have been obtained using intrinsic state formalism introduces variables $$\beta . Gadolinium (Gd) Ruthenium (Ru) isotopic chains taken as examples in illustrating U(5)–SU(3)...
Two-way cross-talk transitions between pairs of signature partners superdeformed (SD) bands in [Formula: see text]Hg (SD2,SD3), (SD3,SD4) and text]T1(SD1,SD2) built on the configurations text], respectively, are proposed. The text] energy staggering presented these odd SD nuclei investigated parametrized by proposing two functions depending dipole linking partners. These differ from conventional employed previous works which depend quadruple within each band. For parametrization, we used...
We investigate the implications of Nambu-Goto (NG), Lüscher Weisz (LW) and Polyakov-Kleinert (PK) effective string actions for Casimir energy width quantum delocalization in 4-dim pure SU(3) Yang-Mills lattice gauge theory. At a temperature closer to critical point T/T c =0.9, we found that next leading-order (NLO) contributions from expansion NG addition boundary terms LW action decrease deviations data intermediate distance scales both quark-antiquark QQ̅ potential broadening color tube...
The width of the quantum delocalization QCD strings is investigated in effective string models beyond free Nambu-Goto approximation. We consider two Lorentzian-invariant boundary-terms L\"uscher-Weisz action addition to self-interaction term equivalent loop order (NG) action. geometrical terms which realize possible rigidity scrutinized as well. perform numerical analysis on 4-dim pure $SU(3)$ Yang-Mills lattice gauge theory at temperature scales near deconfinement point. comparative study...
The bandhead spins of seventeen superdefomed bands in A = 80 – 104 region (38Sr, 39Y, 40Zr, 41Nb,42Mo, 43Tc, 46Pd) have assigned by an indirect method. dynamical moment inertia J(2) as a function rotational frequency ђω are extracted from Harris expansion and fitted to the experimental values using computer simulated search program. calculated dynamic with best optimized parameters integrated give spins. intrinsic aligned angular momentum (the integration constant) is assumed be zero....
