Let \(S^n\) be the unit \(n\)-sphere, \(M=S^1\times S^{n-1}\) (\(n\) even) with the standard Lorentzian or Riemannian metric and nontrivial spin structure on \(S^1\), the standard Riemannian metric and the standard spin structure on \(S^{n-1}\). Spinors and twistors on \(M\) are considered in order to get the eigenvalues of the squares of the Dirac and Rarita-Schwinger operators on \(M\). The computations are based on results of T. Branson [J. Funct. Anal. 106, 314–328 (1992; Zbl 0778.58066); Proc. Am. Math. Soc. 126, 1031–1042 (1998; Zbl 0890.47030); J. Lie Theory 9, 491–506 (1999; Zbl 1012.22026)] and T. Branson and O. Hizaji [“Bochner-Weitzenböck formulas associated with the Rarita-Schwinger operator”, Int. J. Math. 13, No. 2, 137–182 (2002; Zbl 1109.53306), see also arXiv:hep-th/0110014].
