Abstract：
The σ _Rfor ^14,15C and _//of ^13,14C fragments from ¹⁵C, and ¹³C fragments from ¹⁴C breakup have been measured at 83A MeV. FWHMs of _//have been determined to be 71±9MeV/c and 223±28MeV/c for ¹⁴C and ¹³C from ¹⁵C, and 195±21MeV/c for ¹³C from ¹⁴C. The FWHM for ¹³C from ¹⁵C and ¹⁴C are consistent with Goldhaber model's prediction. While the FWHM of ¹⁴C fragments from ¹⁵C is much smaller. An anomalous enhancement from its neighbors has been observed in the measured σ _Rof ¹⁵C. The experimental data are discussed in the framework of the Glauber model. The analysis of both _//and σ _Rdata indicate a dominant s-wave component in the ground state of ¹⁵C.
