Largescale first principles configuration interaction calculations of optical absorption in boron clusters
07 Mar 2012   Contributor(s):: Ravindra L Shinde
We have performed systematic largescale allelectron correlated calculations on boron clustersBn (n=2–5), to study their linear optical absorption spectra. Several possible isomers of each cluster were considered, and their geometries were optimized at the coupledcluster singles doubles(CCSD)...
