摘　　要：The problem of how long it takes for an electron to tunnel from one side of a barrier to the other has been debated for decades and the attoclock is a promising experimental procedure to address this problem.In the attoclock experiment,,many physical effects will contribute to the experimental results and it is difficult to extract the t unneling time accurately.We numerically investigate a method of measuring the residual equivalent temporal offset(RETO)induced by the physical effects except for tunneling delay.The Coulomb potential effect,the nonadiabatic effect,the multielectron effect,and the Stark effect are considered in the theoretical model.It is shown that the ratio of the RETO of the target atoms to that of H is insensitive to the wavelength and is linearly proportional to(2IP)^-3/2.This work can help to improve the accuracy of the attoclock technique.
