Title: {alpha}-cluster states above the threshold energy in {sup 44}Ti

Abstract

The angular distributions of the cross sections of reactions to levels up to {ital E}{sub {ital X}}=11 MeV in {sup 44}Ti were measured for the reaction {sup 40}Ca({sup 6}Li,{ital d}) at {ital E}=37 MeV. These angular distributions for the unbound states, particularly the well populated 7.67(10{sup +}), 8.04(12{sup +}), 8.54, 8.96, 9.58, and 10.86 MeV states, were analyzed together with the data at {ital E}=50 MeV using {alpha}-particle wave functions calculated at the resonance energies using the squared Woods-Saxon potentials. The strongly excited state at {ital E}{sub {ital X}}=10.86 MeV, whose spin parity was not identified from the data at 50 MeV, was found to be a candidate for the bandhead state of the higher nodal {ital K}{sup {pi}}=0{sup +} band with principal quantum number {ital N}=14. {copyright} {ital 1996 The American Physical Society.}
