Low-lying positive parity levels of the isotopes in natural cadmium were Coulomb excited with 2.7--4.2 MeV protons. Eight levels of /sup 111/Cd up to 1130.4 keV and four levels of /sup 113/Cd up to 680.5 keV excitation energy, and the first 2/sup +/ states in even-even isotopes (/sup 110,112,114,116/Cd) were excited. A 50 cm/sup 3/ Ge(Li) detector was used to measure the deexcitation gamma-ray yields. The 1130.4 keV level in /sup 111/Cd had not been investigated earlier through Coulomb excitation. Also the 245.4, 700, 754.9, 855.6, and 1020.7 keV levels in /sup 111/Cd, and the 316.1 keV level in /sup 113/Cd were Coulomb excited with protons for the first time. The reduced E2 transition probabilities B(E2), and partial half-lives T/sub 1/2/ (E2), for various levels were determined. The gamma-ray angular distributions were analyzed to deduce the E2/M1 mixing ratios (delta) for various transitions from the levels in /sup 111,113/Cd. The 700, 754.9, 855.6, and 1020.7 keV levels in /sup 111/Cd, and the 680.5 keV level in /sup 113/Cd have been assigned a spin value of (3/2)/sup +/, while the 1130.4 keV level in /sup 111/Cd has been assigned a spin of (5/2)/sup +/. The results have been compared with existing theoretical and experimental data in the literature.
