Nonyrast high-spin states in N = Z Ti-44 - art. no. 064314

High-spin states have been investigated in the N=Z=22 nucleus Ti-44. A newl y observed set of states with J(pi)=6(+), 8(+), 10(+), and 12(+) are assign ed to be members of a band built upon an excited 0(+) state. This band disp lays rotational-like level spacings, with a near-linear J(J + 1) dependence . A third set of J(pi)=8(+), 10(+), and 12(+) states have also been tentati vely assigned and a negative-parity intruder band has been extended to J(pi )=13(-). Comparisons with df-shell model calculations show a good agreement for both energy levels and branching ratios. These calculations indicate t hat the excited 0(+) band is dominated by a mixture of 8p-4h and 6p-2h conf igurations relative to Ca-40.
