Eigenchannel R-matrix Calculation of the Even-parity 6 Pnp and 6 Pnf J=0,1, 2 Autoionizing Levels of Barium
نویسنده
چکیده
A detailed comparison between theoretical calculations and recent experiments on laser-excited 6pnp and 6pnf J = O , 1.2 autoionizing levels of Ba is presented. All observables are calculated by a combination of the eigenchannel R-matrix and the multichannel quantum defect theory (MQDT) methods. MQDT analyses of the energy positions of the resonances are presented, and the photoionization spectra from low-lying 6s6p’Pn,! or Sd6p’P0,1 levels and from Rydberg levels 6snp ‘P, are investigated.

Theoretical energy-positions of 4fnf J = 5,6 autoionising levels of barium are obtained by a combination of the eigenchannel R-matrix and the Multichannel Quantum Defect Theory (MQDT) methods. High-lying 4fnf J = 5,6 levels (n > 8) located below the
متن کاملCalculation of the rotational bands for the 20Ne isotope
The phenomenon of clustering in light nuclei is one of the interesting topics while its study is difficult. In this article, a simple model (the two-particle model which includes a core and a cluster) is presented for the investigation of the positive and the negative parity of rotational bands of 20Ne isotope. The Deng-Fan and the Hellman potentials are considered as the core and the cluster p...
متن کاملPhysicochemical and Sensory Evaluation of Whole Soybean Curd Supplemented with Pine Needle Powder
To develop functionally and nutritionally improved whole soybean curd (WSC), the effects of partial (0 ~ 4%) replacement with pine needle powder (PNP) on the quality characteristics of WSC were investigated. The moisture content and pH ranged from 76.96~77.80% (wet basis) and 6.69~6.74, respectively, with no considerable differences. Lightness significantly decreased with higher PNP content in ...
متن کاملStrongly clean triangular matrix rings with endomorphisms
A ring $R$ is strongly clean provided that every element in $R$ is the sum of an idempotent and a unit that commutate. Let $T_n(R,sigma)$ be the skew triangular matrix ring over a local ring $R$ where $sigma$ is an endomorphism of $R$. We show that $T_2(R,sigma)$ is strongly clean if and only if for any $ain 1+J(R), bin J(R)$, $l_a-r_{sigma(b)}: Rto R$ is surjective. Furt...
متن کاملElectron impact excitation of the lowest doublet and quartet core-excited autoionizing states in Rb atoms
Electron impact excitation of the (4p5s)P3/2,1/2 and (4p4d5s)P1/2,3/2,5/2 autoionizing states in rubidium atoms was studied experimentally by measuring the ejected-electron excitation functions and theoretically by employing a fully relativistic Dirac B-spline R-matrix (close-coupling) model. The experimental data were collected in an impact energy range from the respective excitation threshold...
