Phys. Rev. Lett. 94, 052502 (2005) [4 pages]Production of the Neutron-Rich Hypernucleus Λ10Li in the (π-,K+) Double Charge-Exchange ReactionReceived 27 August 2004; published 9 February 2005 In order to produce a neutron-rich Λ hypernucleus for the first time, we carried out an experiment by utilizing the (π-,K+) double charge-exchange reaction on a 10B target. We observed the production of a Λ10Li hypernucleus. The cross section for the Λ bound region was found to be 11.3±1.9 nb/sr with the 1.2 GeV/c incident momentum, which is compared with the Λ10B hypernucleus production cross section, 7.8±0.3 μb/sr, in the (π+,K+) reaction with a 1.05 GeV/c incident momentum beam. © 2005 The American Physical Society URL:
