The process of mutual neutralization of 
and H - ions in the CM
collision energy range 
is studied within the
multi-channel Landau-Zener model. From the multitude of covalent 
states only the states 
, 
and
are strongly coupled with the initial ionic 
state. The total mutual-neutralization cross-section has a broad maximum
around 
of about 
, and below
it monotonically increases with decreasing the collision
energy, surpassing a value of 
below 
. The mutual neutralization of 
and H - ions
is, therefore, an important process in cold hydrogen plasmas.
