N2 - Excited states in 150Nd have been investigated with the 150Nd(n,n ′γ) reaction. In addition to the previously known Kπ = 0- band, a new Kπ = 2- band is established, and level lifetimes are determined for all the reported band members. These lifetime data reveal a pattern of enhanced E1 transition strengths, similar to that observed in 152Sm and unprecedented in other nuclei, thus suggesting a systematic pattern for octupole collectivity in the N = 90 isotones. The pattern lies outside of the various model descriptions that have been put forward for nuclei in this or any other region.
