Complex-coordinate calculation of 1De resonances using Hylleraas functions
Abstract
The method of complex-coordinate rotation is used to calculate the lowest-lying 1De resonances below the n=2 and 3 hydrogen thresholds. Hylleraas functions with up to N=1230 terms are used. Resonance parameters for the n=2 resonance are determined as E=-0.255 873 7+/-1×10-6 Ry and Γ=0.000 633 4+/-2×10-6 Ry. The resonance parameters for the n=3 resonance are determined as E=-0.131 906 6+/-1×10-6 Ry and Γ=0.003 316+/-2×10-6 Ry.
