XPS Al K-a and high energy x-ray photoelectron spectroscopy (HAXPES) Cr K-a measurement of bulk boron

Bulk boron was analyzed using both XPS and high-resolution high energy x-ray photoelectron spectroscopy. The spectra of boron obtained using monochromatic Al K-a radiation include survey scan and high-resolution spectra of B 1s, O 1s, N 1s, C 1s, and Ar 2p. The Cr K-a spectra with radiation at 5414.8 eV include survey scan and high-resolution spectra of B 1s, O 1s, N 1s, C 1s, Ar 2p, and Ar 1s.
