Abstract

The angular distributions of the cross sections of reactions to levels up to EX=11 MeV in Ti44 were measured for the reaction Ca40(6Li,d) at E=37 MeV. These angular distributions for the unbound states, particularly the well populated 7.67(10+), 8.04(12+), 8.54, 8.96, 9.58, and 10.86 MeV states, were analyzed together with the data at E=50 MeV using α-particle wave functions calculated at the resonance energies using the squared Woods-Saxon potentials. The strongly excited state at EX=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 Kπ=0+ band with principal quantum number N=14. © 1996 The American Physical Society.
