Let h be a cuspidal Hecke eigenform of half-integral weight, and \(E_{n/2+1/2}\) be Cohen’s Eisenstein series of weight \(n/2 + 1/2.\) For a Dirichlet character χ we define a certain linear combination \(R^{(\chi )}(s,h,E_{n/+1/2})\) of the Rankin–Selberg convolution products of h and \(E_{n/2+1/2}\) twisted by Dirichlet characters related with χ. We then prove a certain algebraicity result for \(R^{(\chi )}(l,h,E_{n/2+1/2})\) with l integers.
