The reactions γp → ηp and γp → η 0 p are measured from their thresholds up to the center-of-mass energy W ¼ 1.96 GeV with the tagged-photon facilities at the Mainz Microtron, MAMI. Differential cross sections are obtained with unprecedented statistical accuracy, providing fine energy binning and full production-angle coverage. A strong cusp is observed in the total cross section for η photoproduction at the energies in the vicinity of the η 0 threshold, W ¼ 1896 MeV (E γ ¼ 1447 MeV). Within the framework of a revised ηMAID isobar model, the cusp, in connection with a steep rise of the η 0 total cross section from its threshold, can only be explained by a strong coupling of the poorly known Nð1895Þ1=2 − state to both ηp and η 0 p. Including the new high-accuracy results in the ηMAID fit to available η and η 0 photoproduction data allows the determination of the Nð1895Þ1=2 − properties.

I would like to thank God for His never-ceasing love and kindness, and for the people who helped me accomplish this work. I would like to express my deep gratitude to my advisor, Professor Steffen Strauch, for his support, guidance, and for the time he spent helping me during this analysis. He continuously inspired me and patiently guided me through all the steps of my research endeavor, and I highly appreciate it. I am also indebted to my dissertation committee members: Professor Ralf Gothe, Professor Camelia Knapp and Professor Milind Purohit for their time, insight, and support. I would also like to thank Professor Yordanka Ilieva for her feedback and assistance. Many thanks also go to the members of FROST g9b group for sharing their knowledge and experience on so many occasions. Last but not least, it was my privilege to be part of the USC experimental nuclear physics group, a wonderful team of researchers who are friendly, generous and supportive.

“…We find that the asymmetry varies significantly over Mandelstam t, demonstrating the need for unnatural pion exchange as well as natural exchanges such as ⇢ and a 2 . This reaction has been of theoretical interest for several decades [8][9][10]; however, most prior measurements have been made at lower energies [11][12][13][14][15]. At energies of E = 1 4 GeV, both t-channel and s-channel processes contribute to single pseudoscalar photoproduction, and often the experimental focus is on s-channel baryon resonances.…”
