研究了N= Z= 22核44 Ti的高自旋态。一组新观察到的J π= 6+、8+、10+和12+的态被指定为建立在激发态0+上的能带的成员。该带显示类似旋转的能级间距，具有接近线性的J（J+ 1）依赖性。第三组J π= 8+，10+和12+态也被暂时指定，并且负宇称入侵带被扩展到J π= 13−。与df-壳模型计算的比较表明，能量水平和分支比都很好的协议。这些计算表明，激发0+带占主导地位的8 p-4 h和6 p-2 h配置相对于40 Ca的混合物。
High-spin states have been investigated in the N= Z= 22 nucleus 44 Ti. A newly observed set of states with J π= 6+, 8+, 10+, and 12+ are assigned to be members of a band built upon an excited 0+ state. This band displays rotational-like level spacings, with a near-linear J (J+ 1) dependence. A third set of J π= 8+, 10+, and 12+ states have also been tentatively assigned and a negative-parity intruder band has been extended to J π= 13−. Comparisons with df-shell model calculations show a good agreement for both energy levels and branching ratios. These calculations indicate that the excited 0+ band is dominated by a mixture of 8 p–4 h and 6 p–2 h configurations relative to 40 Ca.
