摘要：

In a broadband neutrino exposure of the Fermilab 15-ft bubble chamber, we observe the production of the c++(2426) charmed baryon followed by its decay to Λc+(2260) and π+. We find the mass of the Λc+ to be 2257±10 MeV and the m(c++)-m(Λc+) mass difference to be 168±3 MeV. Previously unseen two-body decay modes of the Λc+(2260) are observed. © 1979 The American Physical Society.
