Phys. Rev. C 58, 826–830 (1998)Weak coupling and single-particle structure at high spin in 143NdReceived 20 January 1998; published in the issue dated August 1998 High-spin states of 143Nd have been studied using γ-γ and γ-conversion electron coincidences. The measurement of 16 new transitions and 8 new conversion coefficients allow revision of the high-spin portion of the level scheme and the determination of parities of six levels for the first time. While the yrast states up to J=43/2 can be described using the weak coupling of an f7/2 neutron to the 142Nd core nucleus, the new experimental results suggest that weak coupling breaks down above J=43/2. This behavior may signal that the closed N=82 neutron shell of 142Nd is broken above J=16. © 1998 The American Physical Society URL:
