The (p,n) reaction at 119.3 MeV has been employed to measure the spin transfer strength in /sup 40/ /sup 42/ /sup 44/ and /sup 48/Ca. The experiment was carried out at the Indiana University Cyclotron Facility using the neutron time of flight apparatus and time compensated scintillation detectors at a target-to-detector distance of 131.5 meters. Analyses of the data by several different methods indicate that a significant amount of 1/sup +/ strength is contained in what is conventionally taken as the backgound in neutron energy spectra. This finding explains at best partially the apparent quenching of the spin dependent operator V/sub sigmatau/ when the data were analyzed ignoring such a background. An earlier observation that the 16.8 MeV state in /sup 48/Sc is wider than the parent state in /sup 48/Ca at an excitation of 2.52 MeV is confirmed by the present data. The 2.73 MeV state in /sup 48/Sc is found to have an angular distribution corresponding to L = 0.
