"Hamburan K−n dihitung dengan menggunakan teknik 3D yang dibandingkan dengan perhitungan partial wave untuk memecahkan persamaan Lippmann-Schwinger untuk matriks T. Interaksi yang dipakai melibatkan pertukaran meson dan hyperon sampai orde kedua. Perhitungan dibandingkan dengan yang menggunakan kinematika relativistik untuk melihat efek relativistik pada energi bervariasi. Besaran spin yang dihitung adalah penampang lintang diferensial, polarisasi, dan depolarisasi.

Scattering of K−n is calculated using 3D technique which then is compared with the partial wave calculations to solve the Lippmann-Schwinger equation for matrix T. The interaction being used involves the exchange of mesons and hyperon up to second order. The calculations are compared with those using relativistic kinematics to see relativistic effects on various energies. The spin observables are differential cross section, polarization and depolarization.

"Hamburan K+p dimodelkan sebagai pertukaran satu hadron. Hadron yang dipertukarkan berupa meson skalar σ; meson vektor ρ dan ω; hyperon Λ dan Σ; dan resonans Σ∗ (1385). Besaran yang dihitung adalah spin-averaged differential cross section yang dihitung menggunakan kinematika relativistik serta menggunakan teknik tiga dimensi sehingga tanpa ekspansi gelombang parsial. Penelitian dilakukan untuk melihat kontribusi suku rescattering pada hamburan K+p. Kontribusi suku rescattering dengan melibatkan semua pertukaran partikel dihitung pada energi 700 MeV - 3400 MeV. Kemudian, kontribusi suku rescattering untuk tiap pertukaran partikel dihitung pada energi 700 MeV - 2200 MeV dan energi 5 GeV - 10 GeV.

K+p scattering is modeled as one-hadron exchange. The hadrons being exchanged are scalar meson σ; vector meson ρ and ω; hyperon Λ and Σ; and resonance Σ∗ (1385). Spin-averaged differential cross section is calculated using relativistic kinematics and three-dimensional technique thus without partial wave expansion. The research was conducted to see the contributions of rescattering terms on K+p scattering. Rescattering terms contributions involving all exchanged particles are calculated for energies 700 MeV - 3400 MeV. Furthermore, rescattering terms contributions for each exchanged particles are calculated for energies 700 MeV - 2200 MeV and energies 5 GeV - 10 GeV."

"Hamburan K+n dihitung dalam basis ruang momentum tiga dimensi (3D). Sebagai input digunakan interaksi yang dijabarkan sebagai pertukaran meson dan hiperon antar kaon dan nukleon. Dua tipe perhitungan dikerjakan, tipe satu menggunakan kinematika nonrelativistik dan tipe dua memakai kinematika relativistik. Perhitungan tipe dua dibandingkan terhadap perhitungan tipe satu untuk melihat efek relativistik pada energi yang bervariasi.

K+n scattering is calculated in three-dimensional (3D) momentum space basis. As input interaction described as meson and hyperon exchange between kaon and nucleon is taken. Two types of calculations are carried out, type one uses nonrelativistic kinematics and type two takes relativistic kinematics. Calculations of type two are compared to those of type one to see some relativistic effects at various energies.

Fenomena halo neutron dalam nuklir digambarkan adanya kemunculan 'ekor' dan
adanya 'ruang kosong' antara core dan ekor pada distribusi neutron akibat energi
ikat yang lemah. Metode analisa halo yang dikembangkan oleh V. Rotival dkk [Phys.

del Hartree-Fock-Bogoulibov (HFB) pada isotop Cr dan isotop Sn menjadi salah sa-

menggunakan model Relativistic Mean Field (RMF) pada penelitian ini. Berbeda
dengan hasil perhitungan berdasarkan model HFB, kami fokus mengamati perilaku
spektrum single particle energy level 1g9~2 terhadap kemunculan halo pada isotop
Cr. Selain itu, pada penelitian ini kami juga memperlajari dampak dari suku cross
coupling meson ! − , suku-suku tensor dan suku pertukaran elektromagnetik pada
model RMF terhadap kemunculan halo pada isotop Cr dan isotop Sn. Hasil perhi-
tungan prediksi kemunculan halo berdasarkan model RMF lebih besar dibandingkan

ABSTRACT
In neutron halo phenomenon, the neutron density displays an unusually extended
'tail' and 'empty space' between the core and the tail due to weak binding energy.
New analysis method of the halo was developed by V. Rotival, et al.[Phys. Rev. C79,
054308 (2009)] in Cr-isotopes and Sn-isotopes, its usually applied with Hartree-Fock-
Bogoliubov (HFB) model. Unlike them, we use the model of the Relativistic Mean
Field (RMF) in this research. We observed di erent behavior at the level 1g9~2 in line
with appearance of halo in Cr-isotopes. Moreover, in this research we also studied
the e ects of cross coupling meson ! − , tensor, and electromagnetic exchange in
RMF model appearance of halo in Cr-isotopes and Sn-isotopes. The prediction of
the existence of halo based on RMF model is greater than the prediction based on
HFB model (`NhaloeRMF > `NhaloeHFB):, In neutron halo phenomenon, the neutron density displays an unusually extended

Prediksi dari posisi proton dan neutron dripline dipelajari dalam model Modi ed

Posisi proton dan neutron dripline diprediksi dengan menggunakan energi separasi

kopling isovektor-isoskalar, tensor dan electromagnetic exchange terhadap prediksi
proton dan neutron dripline. Hasil perhitungan menunjukkan bahwa prediksi proton
