Cross section σ4D→4F was measured for the collision transfer process of Na(4D) +Na(3S)→Na(4F)+Na(3S).The 4D state is excited by two-photon absorption using a
A simple,engineeringly feasible dynamic method is supposed to control the deuterium-tritium burn process in Tokamak reactors operated in an advanced scenario.Th
