Neutral products from dissociative collisions of triatomic hydrogen like ions incident on He atoms were studied. Absolute differential and total cross sections are reported in the energy range of 1.25 and 5.00 keV for scattering angles between -5 deg. and 5 deg. The differential cross sections have a decreasing behavior with a slight structure around 2.0 deg. . The total cross sections show no dependence on the projectile mass at equal velocity. The cross sections are between 4x10{sup -17} cm{sup 2} and 2x10{sup -16} cm{sup 2}. A polynomial fit of fourth order was adjusted to the data indicating a maximum at 3.5 keV/amu, and showing an agreement with a previous work for H{sub 3}{sup +} at high energies.
