The low-lying states (
, and 
) of 
system are investigated by using the microscopic Generator Coordinate Method (GCM)-Brink wave functions, in which one simple picture of 
structure is assumed for investigating the character of relative motion of the core 
and the assumed dineutron cluster. By calculating the squared overlap between the GCM-Brink wave functions and the angular-momentum-projected Tohsaki-Horiuchi-Schuck-Röpke (THSR) wave functions in a simple 
model, it is found that the single THSR wave functions characterizing the nonlocalized clustering are almost equivalent to the corresponding GCM-Brink wave functions. The results indicate that the concept of nonlocalized clustering can be extended even in the more-shell-model-like states in nuclei.
