  The recent measurements of high energy photodisintegration of the $^3He$
nucleus to the $pd$ pair at $90^0$ center of mass demonstrated an energy
scaling consistent with the quark counting rule with unprecedentedly large
exponent of $s^{-17}$. To understand the underlying mechanism of this process
we extended the theoretical formalism of hard rescattering mechanism to
calculate the $\gamma ^3He\rightarrow pd$ reaction. In HRM the incoming high
energy photon strikes a quark from one of the nucleons in the target which
subsequently undergoes hard rescattering with the quarks from the other
nucleons generating hard two-body system in the final state of the reaction.
Within the HRM we derived the parameter free expression for the differential
cross section of the reaction, which is expressed through the $^3He\rightarrow
pd$ transition spectral function, cross section of hard $pd\rightarrow pd$
scattering and the effective charge of the quarks being interchanged during the
hard rescattering process. The numerical estimates of all these factors
resulted in the magnitude of the cross section which is surprisingly in a good
agreement with the data.
