Calculation of lifetimes of low-lying odd-parity levels of Sm

Ab initio calculations of E1 transition amplitudes from low-lying odd-parity levels (9)G(J) (J=0-4) and F-9(J) (J=1,2) levels to the even-parity states F-7(J) (J=0-5), H-9(J) (J=1-5), and D-9(J) (J=2,3) were performed using the configuration-interaction method. Using the results obtained for these E1 amplitudes, the oscillator strengths and probabilities of the corresponding transitions were calculated. The estimates of the lifetimes of the odd-parity states are also presented. [S1050-2947(97)06410-X].
