[ABSTRAK
Telah dipelajari dan dikembangkan sebuah model sederhana untuk reaksi fotoproduksikaon pada neutron dari deuteron yaitu model isobar dengan menggunakanpendekatan impuls. Nilai yang dicari adalah nilai penampang lintang diferensialdengan variasi energi foton dimulai dari 1,15 GeV-3,55 GeV. Hasil penelitian inimenunjukkan reaksi + n ! K++􀀀 dapat diektraksi dari reaksi + d ! K++􀀀+ p. Selain itu dapat disimpulkan bahwa hasil penelitian antara data teori dengandata eksperimen berbeda jauh, data teori melampaui jauh diatas nilai data eksperimen.Salah satu faktor yang menyebabkan hasil data teori dengan eksperimenjauh berbeda disebabkan oleh elemen operator dimana nilai elemen operator yangdigunakan memiliki nilai maksimum 2 GeV sedangkan data ekperimen hingga mencapainilai 3 GeV. Hal inilah yang menyebabkan data teori dengan menggunakanmodel missing resonans harus dikalikan dengan faktor pengali agar t dengan hasileksperimen.

ABSTRACT
Has been studied and developed A simple model for reaction of positive kaon onneutron from deuteron in a isobaric model using impulse approximation. The calculationcovered dierential cross section. The value is analyzed with energy rangestart from 1.15-3.55 GeV. The result show that the cross section for + n! K++􀀀can be extracted from the reaction + d ! K+ + 􀀀 + p. The research can beconcluded that the result of theory is over predicted and the one of this factor isoperator elementary that the maximum value we used is 2 GeV, whereas the resultof experiment until 3 GeV. This is make me the theory data using missing resonancemust be times with a times factor to t with the experiment result, Has been studied and developed A simple model for reaction of positive kaon onneutron from deuteron in a isobaric model using impulse approximation.
