We calculate the decay widths of both the second and the third radial excitations of {eta} and {eta}{sup '} within the framework of the {sup 3}P{sub 0} model. After comparing the theoretical decay widths and decay patterns with the available experimental data of {eta}(1760), X(1835), X(2120), and X(2370), we find that the interpretation of {eta}(1760) and X(1835) as the second radial excitation of {eta} and {eta}{sup '} crucially depends on the measured mass and width of {eta}(1760), which is still controversial experimentally. We suggest that there may be sizable pp content in X(1835). X(2120) and X(2370) cannot be understood as the third radial excitations of {eta} and {eta}{sup '}. X(2370) is probably a mixture of {eta}{sup '}(4{sup 1}S{sub 0}) and glueball.
