The giant oxygen isotope shift of the temperature of the ferromagnetic phase transition is calculated in La0.8Ca0.2MnO3 taking into account the values of the bandwidth, the Jahn-Teller polaron energy and the value of the stretching Mn-O optical phonon frequency. The obtained result is close to the experimental one.
