The problem of electron transition in photoelectric effect is treated using a model of a finite potential well.All possible types of exciting by doule photon are disscussed.Also,the ratio of the transition probability excited by double photon to that excited by a single photon is calculated and the numerical solution is found within the range of Fermi level and work function of various common metals.The rate is about 10~(-7) ～10~(-9) ,and this means that,in fact,it is impossible that an electron is excited...
