We examine the use of the WKB approximation to determine the p-wave scattering length. For this we solve the p partial wave Schrödinger equation and analyse the validity of adopting the semiclassical solution to evaluate the constant factors in the solution. We also calculate the p-wave scattering lengths of 6Li and 40K for the a3Σ+u and X1Σ+g states respectively using the variable phase method. The p-wave scattering lengths of 132Cs and 134Cs are also calculated. Based on our calculations, the value of the p-wave scattering lengths of 6Li and 40K are -36ao and -95ao respectively.
