The burning kinetics of dense hot plasma of composition D+D, D+T, D+ 3 He in devices with inertial-magnetic confinement concept is considered. Calculations of the burning kinetics of main fusion reactions in plasma with use of modern refined data on reaction rates at the appropriate temperatures and several types of energy loss for radiation have been made. An analysis of the energy yield is performed taking into account the change in plasma temperature and the heating of burning area in equilibrium plasma, which is described by Maxwell distribution, as well as the analysis of energy exchange between two adjacent burning volumes with different temperatures. Based on all the data found, estimates of the burning properties of plasma in thermonuclear devices with inertial-magnetic confinement of plasma have been made.

The ground-state static observables and elastic longitudinal (charge) form factors of the 9 Be nucleus in the ground and excited states are considered. The calculations were performed in the framework of the dynamic three-particle 2α+n-model of the 9 Be nucleus with the Pauli projection. The ground state of the 9 Be nucleus has been calculated in two models distinguished by the α-α interaction-model 1 (Ali-Bodmer potential) and model 2 (Buck-Friedrich-Wheatley potential). For the excited states of 9 Be, wave functions with Ali-Bodmer potential for the α-α interaction are utilized.
