Resumo: We will discuss the use of the semi-classical method proposed by Minahan (hep-th/0209047) for studying the pulsating string. We use this method to quantize and calculate the tunnelling rate of the pulsating string in the deformed flat space-time. Furthermore, we discuss the classical stability of the this string.
