Abstract

Discrete yrast transitions from states with spins up to

30 ℏ

have been observed in

{}^{158}{Er}

from

{}^{40}{Ar}

-induced compound-nucleus reactions. A second discontinuity in the level sequence occurs around

I = 28 ℏ

. Possible causes and implications of this effect are discussed.
