[ABSTRAK
Semakin baik dan banyaknya hasil eksperimen di bidang nuklir, menjadi faktor pendorongbagi fisikawan nuklir untuk melakukan penelitian lebih lanjut mengenai interaksidan struktur nuklir. Alhasil, banyak reaksi yang bertujuan untuk menjelaskan,membandingkan bahkan memperkirakan hal ini, salah satunya adalah fotoproduksikaon netral pada deuteron. Telah dipelajari sebuah model sederhana untuk reaksifotoproduksi kaon netral pada deuteron yaitu model isobar dengan menggunakanpendekatan impuls. Penelitian ini bertujuan untuk mempelajari penampang lintangeksklusif dan inklusif dari fotoproduksi kaon netral pada deuteron dengan beberapakeadaan kinematik, dan dibandingkan dengan eksperimen [6]. Hasil yang didapatkanmenunjukkan penampang lintang inklusif lebih besar daripada penampang lintangeksklusif karena pada penampang lintang inklusif hanya mendeteksi kaon saja, danuntuk penampang lintang eksklusif mendeteksi kaon dan hiperon secara simultan,makin banyak partikel yang dideteksi makin kecil penampang lintangnya. Penampanglintang eksklusif dengan momentum proton = 0 lebih besar dibandingkan denganmomentum proton tidak nol, hal ini dikarenakan peluang terjadinya reaksilebih besar ketika neutron dalam deuteron diam. Untuk penampang lintang eksklusifdengan variasi momentum proton, paling besar penampangnya berada pada arahsumbu Z, yaitu searah dengan masuknya proyektil foton riil saat terjadinya reaksi.Kaon paling banyak mengalami hamburan pada sudut kecil, sementara pada sudutyang besar penampang lintangnya kecil. Amplitudo transisi deuteron berperan pentingdalam reaksi eksklusif maupun inklusif yaitu dalam menentukan puncak-puncakkurva penampang lintang tersebut.
ABSTRACT
The abundance experimental results in the nuclear eld, becomes a driving factor fornuclear physicists to conduct further research on interactions and nuclear structure.As a result, many reactions aims to explain, compare and even estimate it, one ofwhich is the neutral kaon photoproduction on deuteron. It has been studied a simplemodel for the reaction of the neutral kaon photoproduction on deuteron with isobarsmodel using impulse approximation. This research aims to learn the exclusiveand inclusive cross section of neutral kaon photoproduction on deuteron with somekinematic state, and compared with experiments [6]. The results obtained indicatethe inclusive cross section larger than the exclusive cross section because for theinclusive cross section only detect kaon, and exclusive cross section detect kaon andhyperon simultaneously, more particles are detected the smaller cross section will be.Exclusive cross section with proton momentum = 0 is larger than when proton momentumis not zero, because of the possibilty for greater reaction is when a neutronin the deuteron is not moving. For the exclusive cross section with variation protonmomentum, the largest cross section is in the axis-Z, that have the same directionwith the entry of projectile photon real. Kaon experiences the most scattering atsmall angles, while at large angles have a small cross section. Transition amplitudeon deuteron plays an important role in the reaction that exclusive or inclusive indetermining the peaks of the cross section of the curve, The abundance experimental results in the nuclear eld, becomes a driving factor fornuclear physicists to conduct further research on interactions and nuclear structure.As a result, many reactions aims to explain, compare and even estimate it, one ofwhich is the neutral kaon photoproduction on deuteron.
