ABSTRAKSemakin baik dan banyaknya hasil eksperimen di bidang nuklir, menjadi faktor pendorong
bagi fisikawan nuklir untuk melakukan penelitian lebih lanjut mengenai interaksi
dan struktur nuklir. Alhasil, banyak reaksi yang bertujuan untuk menjelaskan,
membandingkan bahkan memperkirakan hal ini, salah satunya adalah fotoproduksi
kaon netral pada deuteron. Telah dipelajari sebuah model sederhana untuk reaksi
fotoproduksi kaon netral pada deuteron yaitu model isobar dengan menggunakan
pendekatan impuls. Penelitian ini bertujuan untuk mempelajari penampang lintang
eksklusif dan inklusif dari fotoproduksi kaon netral pada deuteron dengan beberapa
keadaan kinematik, dan dibandingkan dengan eksperimen [6]. Hasil yang didapatkan
menunjukkan penampang lintang inklusif lebih besar daripada penampang lintang
eksklusif karena pada penampang lintang inklusif hanya mendeteksi kaon saja, dan
untuk penampang lintang eksklusif mendeteksi kaon dan hiperon secara simultan,
makin banyak partikel yang dideteksi makin kecil penampang lintangnya. Penampang
lintang eksklusif dengan momentum proton = 0 lebih besar dibandingkan dengan
momentum proton tidak nol, hal ini dikarenakan peluang terjadinya reaksi
lebih besar ketika neutron dalam deuteron diam. Untuk penampang lintang eksklusif
dengan variasi momentum proton, paling besar penampangnya berada pada arah
sumbu Z, yaitu searah dengan masuknya proyektil foton riil saat terjadinya reaksi.
Kaon paling banyak mengalami hamburan pada sudut kecil, sementara pada sudut
yang besar penampang lintangnya kecil. Amplitudo transisi deuteron berperan penting
dalam reaksi eksklusif maupun inklusif yaitu dalam menentukan puncak-puncak
kurva penampang lintang tersebut.
ABSTRACTThe abundance experimental results in the nuclear eld, becomes a driving factor for
nuclear physicists to conduct further research on interactions and nuclear structure.
As a result, many reactions aims to explain, compare and even estimate it, one of
which is the neutral kaon photoproduction on deuteron. It has been studied a simple
model for the reaction of the neutral kaon photoproduction on deuteron with isobars
model using impulse approximation. This research aims to learn the exclusive
and inclusive cross section of neutral kaon photoproduction on deuteron with some
kinematic state, and compared with experiments [6]. The results obtained indicate
the inclusive cross section larger than the exclusive cross section because for the
inclusive cross section only detect kaon, and exclusive cross section detect kaon and
hyperon simultaneously, more particles are detected the smaller cross section will be.
Exclusive cross section with proton momentum = 0 is larger than when proton momentum
is not zero, because of the possibilty for greater reaction is when a neutron
in the deuteron is not moving. For the exclusive cross section with variation proton
momentum, the largest cross section is in the axis-Z, that have the same direction
with the entry of projectile photon real. Kaon experiences the most scattering at
small angles, while at large angles have a small cross section. Transition amplitude
on deuteron plays an important role in the reaction that exclusive or inclusive in
determining the peaks of the cross section of the curve, The abundance experimental results in the nuclear eld, becomes a driving factor for
