Abstract

{Nd}^{139 m}

in its

ε

decay preferentially populates a multiplet of six high-lying, high-spin, odd-parity states in

\Pr^{139}

. We interpret this as

{(π d_{\frac{5}{2}})}^{2} {(ν d_{\frac{3}{2}})}^{- 2} {(ν h_{\frac{11}{2}})}^{- 1} \to (π d_{\frac{5}{2}}) {(ν d_{\frac{3}{2}})}^{- 1} \times {(ν h_{\frac{11}{2}})}^{- 1}

, with the

\Pr^{139}

states being three-quasiparticle states.
