Levels in /sup 63/Cu up to an excitation energy of 2.8 MeV were studied through the /sup 63/Cu(p,p'..gamma..) reaction at an incident proton energy E/sub p/ = 5.0 MeV. Singles ..gamma..-ray spectra were obtained with a high resolution Ge(Li) detector at angles of observation theta/sub ..gamma../ = 0/sup 0/, 30/sup 0/, 55/sup 0/, 70/sup 0/, 90/sup 0/, and 125/sup 0/ and a second (monitor) Ge(Li) fixed at THETA/sub ..gamma../(monitor) = 90/sup 0/. The lifetimes of 18 levels were determined through the Doppler shift attenuation method by studying the systematic energy shift of ..gamma..-ray peaks in the angular distribution data. The analysis of angular distributions yielded multipole mixing ratios and J/sup ..pi../ values for several states. The experimental information, wherever complete, was employed to calculate reduced transition probabilities. The results obtained here are compared with theoretical predictions in the framework of the weak-coupling model.
