Phys. Rev. Lett. 89, 132501 (2002) [4 pages]Large Angle Elastic Alpha Scattering on a N=Z Nucleus above A=40Received 6 May 2002; published 5 September 2002 Scattering of alpha particles from 44Ti, 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 40Ca and other light alpha-particle nuclei is not observed. Instead, the backward yield is similar to that observed for other nuclei heavier than 40Ca, and is well described with average optical model parameters. © 2002 The American Physical Society URL:
