Planckian Scattering Beyond the Eikonal Approximation in the Quasi-potential Approach
Nguyen Suan Han, Nguyen Nhu Xuan
Asymptotic behavior of the scattering amplitude for two scalar particles by scalar, vector and tensor exchanges at high energy and fixed momentum transfers is reconsidered in quant…

The Conversion of Gravitons into Photons in Mode
Nguyen Suan Han, Hoang Ngoc Long, Dang Van Soa
We consider the conversion of gravitons into photons in the mode. Cross sections in different directions are given.
