Abstract

Triple-γ coincidence data were used to study the γ-vibrational bands to 14⁺ in ^104-106Mo, to 13⁺ in ^108,110Ru and 17⁺ in ¹¹²Ru, and to 13⁺, 15⁺ in ^112-116Pd. The even-odd spin energy level splittings show rapid variations with spin and neutron number in these nuclides. With one exception, the Sm-Pt nuclei show no such reversal and much smaller staggering.
