Reconciliation of Theoretical Lifetimes of the 5s5p3P2oMetastable State for 88Sr with Measurement:The Role of the Blackbody-Radiation-Induced Decay
文献摘要：
We conducted measurement and calculation to resolve the long-standing large discrepancy in the metastable state lifetime for the 88Sr atom between theoretical and experimental results.The present lifetime τ=830+-240 s,measured using the magneto-optical trap as a photon amplifier to detect the weak decay events,is approximately 60％larger than the previous experimental value τ=520+-140 s.By considering the electron correlation effects in the framework of the multiconfiguration Dirac-Hartree-Fock theory,we obtained a theoretical lifetime of 1079(54)s,which lies in the range of measurements with error bars.Furthermore,we considered the higher-order electron correlation and Breit interaction to control the uncertainty of the theoretical calculation.The significant improvement in the agreement between calculations and measurements is attributed to the updated blackbody radiation-induced decay rate.
