One- and two-neutron removal reactions from the most neutron-rich carbon isotopes

Understand

The structure of $^{19,20,22}$C has been investigated using high-energy (about 240 MeV/nucleon) one- and two-neutron removal reactions on a carbon target.

• Measurements were made of the inclusive cross sections and momentum distributions for the charged residues.
• Narrow momentum distributions were observed for one-neutron removal from $^{19}$C and $^{20}$C and two-neutron removal from $^{22}$C.
• Two-neutron removal from $^{20}$C resulted in a relatively broad momentum distribution.
