SA CASSCF and R matrix calculations of low energy electron collisions with DNA bases and phosphoric acid
... At first the SE and SEP models employed the 6-31G, cc-pVDZ and aug-cc-pVDZ basis sets, whereas the CC calculations used the aug-cc-pVDZ basis set. However, the aug-cc-pVDZ basis set was fount to be too diffuse for ...

Validity of the ICFT R-matrix method : Be-like Al 9+ a case study
... Where does that leave us with regard to the discrepancies noted by Aggarwal & Keenan (2015a)? The concern of Aggar- wal & Keenan (2015a) was the disagreement between R-matrix calculations of ...

Electron impact excitation of neutral boron using the R matrix with pseudostates method
... The RMPS cross sections for transitions from the groundstate to higher n shells in neutral atomic systems will exhibit more pseudoresonance structure as the magnitude of the background cross section weakens. It has been ...

R-matrix electron-impact excitation data for the B-like iso-electronic sequence
... Emission lines of boron-like ions have been recorded in both ear- lier spacecraft (Malinovsky & Heroux 1973; Huber et al. 1973; Acton et al. 1985) and more recent Hinode/EIS (Brown et al. 2008; Landi & Young ...

Low energy electron scattering with the purine bases of DNA/RNA using the R matrix method
... R-matrix calculations on electron collisions with the purine bases found in DNA and RNA (i.e., adenine and guanine) are presented. Resonant anion states of these systems are identified by employ- ing ...

R-matrix electron-impact excitation data for the Na-like iso-electronic sequence
... As noted in the work of Witthoeft et al. (2007), the level mixing effect for higher excited levels strongly affects the behaviour of the Υ along the sequence. Similar level- ordering cross was identified by Liang et al. ...

On the validity of the ICFT R-matrix method : Fe xiv
... A 98 term LS-coupling R-matrix calculation was carried out by Liang et al. so as to span all terms of the first 16 configurations, and so a few ‘CI’ terms were actually included in the LS CC expansion. ...

On the origin of dual Lax pairs and their r-matrix structure
... Combining the results of the present paper (purely algebraic) with the previous results of [7] (purely field theoretic), we are naturally led to suggest that the classical r-matrix has a funda- mental ...
