لقد قمنا بدراسة تحليلية نظرية للحاجز الكولوني,مفهوم عامل التصادم,مفهوم المسار,و مفهوم زاوية grazing في تصادم النوى الثقيلة المرافقة لعامل التصادم و ذلك من أجل العديد من الجمل المتناظرة A1 يساوي A2 و الجمل اللامتناظرة A1 لا يساوي A2 . إن النتائج التي تم الحصول عليها و المعروضة لأول مرة بهذا الأسلوب,تساعد على التمييز بين قوة التأثير المتبادل الكهربائي و قوة التفاعل النووي , و من ثم تحديد طاقة القذف التي يجب استخدمها من أجل إظهار التفاعل المراد دراسته.هذا من ناحية و من ناحية أخرى هذا يساعد على اختيار الكواشف التي يجب أن تستخدم في العمل التجريبي,و من ثم أين يجب أن توضع هذه الكواشف.
We have a detailed analytical study of the Coulomb barrier, the concept of collision factor, the concept of the trajectory,
and the concept of grazing angle in a collision between heavy nuclei, and that for many of the symmetrical systems A1 equal A2
and asymmetric systems A1 doesn't equal A2 .The results obtained and presented for the first time in this way, help to differentiate between the electric interaction and the nuclear reaction, and then determine the energy ejaculation that should be used in order to show the interaction to be studied. On the one hand, on the other hand this helps to choice the detector (or
detectors) that must be used in experimental work, and then where to put this detector (or these detectors).

Choosing of sprinkler trajectory angle and estimation of its
changing is an important factor in sprinkling irrigation systems.
Farmers choose sprinklers with small trajectory angle when they
used treatment wastewater, or water is spraying below tree canopy.
while sprinklers with high trajectory angle used when spraying
above canopy.
