ff365427x19	Chrysovalantis Constantinou	Natural Orbitals for the No-Core Configuration Interaction Approach	1904		.txt	text/plain	189	9	30	The convergence of the ground and excited state energies, radii, and electromagnetic observables of He, Li, and Be isotopes calculated using natural orbitals in ab initio NCCI calculations is discussed. The natural orbital basis builds in contributions from high-lying oscillator shells, thus accelerating convergence of wave functions, energies, and other observables.	cache/ff365427x19.txt	txt/ff365427x19.txt
