[en] The analysis of SU(5) mode is carried out under the assumptions of m_o, m_g<1 TeV and M_H3<3M_G, where m_o is the universal scalar mass, m_g the gaugino mass, M_H3 the Higgs triplet mass and M_G the unification mass. The combined experimental constraints from LEP and CDF on the SUSY mass spectrum and the experimental proton lifetime constraint from Kamiokande are imposed. Under the above constraints masses of the 31 supersymmetric particles are determined in terms of the four parameters, and these masses are strongly correlated. Thus the theory predicts that either a neutral Higgs or a light Wino will be observable at LEP2. The No-Scale model is found to be phenomenologically not viable as it violates the proton life-time limits under the assumed theoretical constraints. (R.P.) 12 refs.; 2 figs
