We measured the 
reaction spectra at 1.8 GeV/ for the graphite and the polyethylene targets in the J-PARC E05 pilot experiment. By comparing the spectra for these two targets, it was found that 
in the 
B nucleus is quite broadened. Furthermore, we also compared broadness of with 
obtained in the 
spectrum. seems to be much more broadened in nuclei than . We gave a possible interpretation, which is related to compositeness of decuplet baryons, for this situation.
