High-spin states of 165Er were studied using the 160Gd(9Be, 4n)reaction at beam energies of 42 and 45 MeV. The previously known bands based on the γ5/2-[523] a
The line shapes to observe ηc in charmonium transitions, I.e.,ψ(2S), J/ψ→γηc, are investigated. The ηc line shapes in exclusive decays or by observing th
