Abstract

Large angle elastic scattering of alpha particles from ⁴⁴Ti, which is the lightest unstable alpha-particle nucleus above A=40, was measured at backward angles. The angular distributions of elastic scattering of alpha particles from ⁴⁰ and ⁴⁴Ti were compared. Results indicated that for ⁴⁰Ca, at angles close to 180^° elastic cross sections higher than Rutherford values were confirmed, while corresponding yields for ⁴⁴Ti were about a factor 20 smaller. An optical model analysis of α+⁴⁴Ti data produced parameters which were in good agreement with the results.
