摘要：

Low-lying low-spin collective states in even Cd-106-112 and Cd-116 were investigated using in-beam and off-beam gamma-ray and conversion-electron spectroscopy. New spin assignments and decay branching ratios for the levels in Cd-106, Cd-108, Cd-110, and Cd-112 were obtained. The present results essentially complement the level systematics from Cd-106 to Cd-120. From the new data, it is inferred that two sets of low-lying 0+ states having different excitation characteristics cross between Cd-114 and Cd-116. No corresponding crossing occurs on the neutron deficient side. New evidence for the existence of the proton-intruder states has been found.
