We present results of submillimeter observations of a low-mass young stellar objects ( YSOs ) condensation in the Cederblad 110 region of the Chamaeleon I dark cloud with Atacama Submillimeter Telescope Experiment .
Our HCO ^ { + } ( J =4-3 ) map reveals a dense molecular gas with an extent of \sim 0.1 pc , which is a complex of two envelopes associated with class I sources Ced110 IRS4 and IRS11 and a very young object Cha-MMS1 .
The other two class I sources in this region , IRS6 and NIR89 , are located outside the clump and have no extended HCO ^ { + } emission .
HCO ^ { + } abundance is calculated to be 2.6 \times 10 ^ { -10 } for MMS1 and 3.4 \times 10 ^ { -9 } for IRS4 , which are comparable to the reported value for other young sources .
Bipolar outflows from IRS4 and IRS6 are detected in our ^ { 12 } CO ( J =3-2 ) map .
The outflow from IRS4 seems to collide with Cha-MMS1 .
The outflow has enough momentum to affect gas motion in MMS1 , although no sign has been detected to indicate that a triggered star formation has occurred .
