Scattering of alpha particles from {sup 44}Ti, the lightest unstable alpha-particle nucleus above A=40, has been measured at backward angles. The 'anomalous' order-of-magnitude enhancement that is characteristic of {sup 40}Ca and other light alpha-particle nuclei is not observed. Instead, the backward yield is similar to that observed for other nuclei heavier than {sup 40}Ca, and is well described with average optical model parameters.
