摘要

Lifetimes of excited states in ¹⁰⁰Ru were determined from Doppler-shift attenuation measurements following the ¹⁰⁰Ru(n,n^′γ) reaction. Absolute transition rates or limits thereon were extracted for states in the three-phonon region and were compared with an interacting boson model description of this nucleus. Intruder states were identified, and a candidate for the 2⁺ mixed-symmetry state is suggested.
