Preliminary differential cross-sections of the reactions 
and 
with A = 1
H, 12
C, and
nat
Pb are presented. A significant nuclear-mass dependence of the invariant-mass distribution is found in the 
channel. The dependence is not observed in the 
channel. The in-medium observation in the channel is consistent with an in-medium modification of the interaction in the I = J = 0 channel, changing width and pole position of a resonant state.
