Inspired by a large decay branching ratio (BR) of B+βf0β(980)K+
measured by Belle recently, we propose that a significant evidence of the
component of nnΛ=(uuΛ+ddΛ)/2β in f0β(980) could be
demonstrated in exclusive bβc decays by the observation of f0β(980) in
the final states BΛβD0(β)Ο+Οβ(KK) and BΛβJ/Ξ¨Ο+Οβ(KK). We predict the BRs of BΛβD0(β)(J/Ξ¨)f0β(980) to be O(10β4) (O(10β5)) while
the unknown wave functions of D(β)0 (J/Ξ¨) are chosen to fit the
observed decays of BΛβD(β)0Ο0(J/Ξ¨K0(β)).Comment: 4 pages, 2 figures, Revtex4, version to appear in PR
