Coulomb shift of the 10Be and 10C nuclei, which can be nicely described by the α + α + N + N four-body degrees of freedom, is investigated by the microscopic cluster model. The Coulomb shift is prominent for the non S-wave configurations, while the shift is suppressed for the S-wave dominant configurations, which have the welldeveloped α cluster structure. This result can be interpreted in terms of the so-called Thomas-Ehrman shift, which is originally discussed in the Coulomb shift of the 17O–17F systems.
