Heat equation (cylindrical)

I have tried to solve the cylindrical case of the heat equation and reached the second order differential equation for the function R(r):

R'' + (1/r)*R' + (alfa/k)*R = 0

(alfa, k are constants)

I couldn't find material on the web for non-constant coefficients, does anyone know how to solve this?

thanks
