IN THIS FOUR-YEAR NASA HELIOPHYSICS LIVING WITH A STAR (H-LWS) PROJECT I PROPOSE TO CONDUCT A SYSTEMIC DATA ANALYSIS AND MODEL CALCULATIONS TO EXAMINE THE CAUSE OF THE DOUBLE POWER-LAW SPECTRA OF THE SOLAR ENERGETIC PARTICLES (SEP). SPECIFICALLY I PROPOSE TO INVESTIGATE THE CURRENT EXISTING TWO HYPOTHESIS: (1) THE DOUBLE POWER-LAW ENERGY PROFILE IS GENERATED CLOSE TO THE SUN DUE TO THE ACCELERATION PROCESS IN THE STANDARD DSA THEORY (2) THE DOUBLE POWER-LAW SPECTRA ARE DUE TO THE TRANSPORT PROCESS FROM THE SUN TO 1 AU. IN THE STANDARD DSA THEORY A BROKEN POWER LAW IS PREDICTED DUE TO THE RIGIDITY DEPENDENT ESCAPING PROCESS BECAUSE OF THE FINITE SHOCK SIZE OR THE LIMITED ACCELERATION TIME. THE MAXIMUM CHARACTERISTIC ENERGY (I.E. BREAK ENERGY) IS CALCULATED ACCORDING THE SHOCK SIZE OR THE ACCELERATION TIME LIMIT WHICHEVER IS SMALLER. BELOW THE CHARACTERISTIC ENERGY A STEADY STATE DSA POWER-LAW SPECTRUM IS OBTAINED WHILE THE POWERLAW SPECTRUM STEEPENS BEYOND THE CHARACTERISTIC ENERGY. IN THE INTERPLANETARY TRANSPORT HYPOTHESIS THE DOUBLE POWER-LAW IS CAUSED BY THE DIFFUSION PROCESS. LOW-ENERGY PARTICLES EXPERIENCE MORE DIFFUSION AND HOLDING AND ARRIVE AT THE OBSERVER LATER THAN THE HIGH-ENERGY PARTICLES IN WHICH CASE A STEADY STATE DSA POWER-LAW SPECTRUM AT HIGH-ENERGY END WITH ROLLOVER AT LOW-ENERGY END IS OBTAINED. THE PROPOSED RESEARCH FOCUSES ON FINDING THE ORIGINS AND DETERMINING THE RELATIVE IMPORTANCE OF THE ACCELERATION AND TRANSPORT PROCESS IN BREAKING THE ENERGY SPECTRA.
