In this report arguments are presented to classify this hadron rich event as an interaction event and the consequences of this statement .
For instance the total invariant mass would be estimated as \approx 61 GeV/c ^ { 2 } and the pair of hadrons used for height estimation have invariant mass = 2.2 GeV/c ^ { 2 } .
Besides , tables showing the parametric and non-parametric analysis resulting in a criteria table and the resulting tables for the discrimination of \gamma or hadron induced showers were presented at the 16 ^ { th } ISVHECRI , held at Batavia , USA .
The main point of hadron rich and Centauro events is the identification of the nature of the observed showers .
The identification and energy determination of \gamma or hadron induced showers was made using 2 simulations .
Complemented with the observation of photosensitive material under microscope it was determined that the event C16S086I037 could be classified as a hadron rich event .
We used 10 reasonable scenarios for \gamma /hadron discrimination and obtained that the event is composed of 25 \gamma ’ s , 36 hadrons and 1 surviving and leading hadron .
All these scenarios were reported at the 14 ^ { th } ISVHECRI , held in Weihai , China and resulted in rather constant values of physical quantities , like the mean transverse momentum of hadrons , < P _ { T _ { h } } > , and the mean inelasticity of \gamma -ray , < k _ { \gamma } > .
Assuming that the most energetic shower is the surviving particle of an interaction and the tertiary produced particles are from normal multiple pion production , the characteristics of the interaction are : Energy of primary particle E _ { 0 } = 1 , 061 TeV , Inelasticity of collision K = 0.81 , Mean inelasticity of \gamma -ray < k _ { \gamma } > = 0.27 , Hadron induced showers energy/Total energy Q ^ { \prime } _ { h } = 0.90 \approx Q _ { h } = 0.71 , Rapidity density N _ { h } / \Delta Y = ( 8.56 - 9.89 ) , Mean energy of secondary hadrons < E _ { h } > = ( 21.5 \pm 4 ) TeV , Mean transverse momentum < P _ { T _ { h } } > = ( 1.2 \pm 0.2 ) GeV/c , Upper bound of partial cross section \sigma \leq ( 0.32 - 0.85 ) mb and life time \tau \leq 10 ^ { -12 } s .
