This paper reports the first evidence of non-thermal phase
transition in the target fragmentation of
- interactions at 14.5
.
Factorial moment analysis has been performed in two dimensions
taking into consideration the anisotropicity of the phase space.
A signal of non-thermal phase transition is obtained by carrying
out the investigation at that partitioning of phase space where
the anisotropic scaling (self-affinity) behavior of dynamical
fluctuation is best revealed. A signal of multifractality is also
observed from the knowledge of anomalous fractal dimension dq
extracted from the intermittency exponent 
at the
anisotropic phase space scenario.
