Abstract：
In this paper, considering the quantum effect of electrons in a super-strong magnetic field, the influence of a super-strong magnetic field on the chemical potential of a non-zero temperature electron is analyzed, the rates of β decay under the super-strong magnetic field are studied, and then we compare them with the case without a magnetic field. Here, the nucleus ⁶³Co is investigated in detail as an example. The results show that a magnetic field that is less than 10¹⁰T has little effect on the electron chemical potential and β decay rates, but the super-strong magnetic field that is greater than 10¹⁰T depresses the electron chemical potential and improves the β decay rates clearly.
