Based on 6.1 fb^{-1} of e^{+}e^{-} annihilation data collected at center-of-mass energies from 4.600 to 4.843 GeV with the BESIII detector BEPCII collider, a partial wave analysis Λ_{c}^{+}→Λπ^{+}η is performed, and branching fractions decay asymmetry parameters intermediate processes are determined.

We present measurements of the charmonium state h(c)(1P(1)) made with 106x10(6) psi' events collected by BESIII at BEPCII. Clear signals are observed for psi'-->pi0 h(c) and without subsequent radiative decay h(c)-->gamma eta(c). First absolute branching ratios B(psi'-->pi0 h(c)) = (8.4+/-1.3+/-1.0) x 10(-4) B(h(c)-->gamma eta(c)) (54.3+/-6.7+/-5.2)% presented. A statistics-limited determination previously unmeasured width leads to an upper limit Gamma(h(c))<1.44 MeV (90% confidence)....
