The use of the <sup>38</sup>Ar( alpha ,n gamma )<sup>41</sup>Ca reaction has enabled rigorous spin assignments to be made for five high-spin states: 3369 keV (J<sup>pi </sup>=<sup>11</sup>/<sub>2</sub><sup>+</sup>); 3830 (<sup>15</sup>/<sub>2</sub><sup>+</sup>); 3914 (<sup>13</sup>/<sub>2</sub><sup>+</sup>); 3976 (<sup>11</sup>/<sub>2</sub><sup>+</sup>) and 4519 (<sup>13</sup>/<sub>2</sub><sup>+</sup>). An E3 transition strength of 24 (+5,-3) Weisskopf units for the 3369 to 0 keV transition encourages a description of the positive parity states by the weak coupling of a 1f<sub>7/2</sub> neutron to the 3<sup>-</sup> and 5<sup>-</sup> vibrations in <sup>40</sup>Ca.
