Description

We observed well-separated 1s and 2p π- states in 205Pb in the 206Pb( d, 3He) reaction at Td=604.3 MeV . The binding energies and the widths determined are B1s=6.762±0.061 MeV , Γ1s=0.764+0.171-0.154 MeV , B2p=5.110±0.045 MeV , and Γ2p=0.321+0.060-0.062 MeV . They are used to deduce the real and imaginary strengths of the s -wave part of the pion-nucleus interaction, which translates into a positive mass shift of π- in 205Pb
