Ultra Intense Laser UIL interaction with Al27 target could possibly give rise to a nuclear reaction of the target nuclei with the accelerated target charged ion in the laser field. The residual radioactive nuclei of Mn 52 and Mn 51 could well be due to evaporation of deuterons and tritons from the created compound nucleus according to the nuclear reaction: Al27 (Al27, H2) Mn52 and AL27 (Al27 + H3) Mn51 We here will report simulation of compound nucleus formation followed by particle evaporation applying Mont Calro code PACE-4 to estimate the possible crosssection for forming highly excited compound nucleus Fe54 leading to the final Nuclei Mn52 and Mn51. The results shown in the figure below indicate that the highest cross section of such possible two reactions is peaking at Al27 ions projectile energy ≈ 60 MeV (2.222 MeV/ A ) and 70 MeV ( 2.593 MeV/A ) respectively. The cross sections for production of the neutron deficient Mn nuclei resulting from the two above mentioned nuclear reactions of Al27 + Al27 are also estimated. The estimated cross-section of Mn52 and Mn51 positron emitters shown in figure indicate maximum values of approximately 30 and 150 mb at the aluminum ion energies mentioned above respectively. The nuclear reactions leading to Mn positron emitters are expected to also provide deuterons and tritons with the same cross-sections. The energies of these particles (H2 and H3) are calculated considering the newest standard Tables of the Nuclear Masses. Possible acceleration of these emitted particles in the laser field is also expected. The Possibility of a new approach of fusion of the deuterons and tritons without implosion during the confined short laser pulse duration is proposed. In this approach an intense laser field equal or above 100 Peta Watt would be needed. Simulation calculations for the form factors will be reported. The design of the experimental set up to be applied to attain such Fusion energy and overcome probable difficulties will be elaborated.
