Calculation of current induced by photon momentum in gaseous argon

Nondipolar photoelectron angular distributions

“…This difference is caused by the mutual screening of the electrons and would be absent in a simple hydrogenic model (cf. [7,121).…”

“…The M1 interaction acts only on the angular and spin part, but not on the spatial part of the electron's wavefunction, and thus, depending on the theoretical model, either vanishes or contributes very little. Consequently, the next-higher level of approximation to the dipole approximation includes the even-pari ty electric-quadrupole interaction up to terms of order Z a [7,12,131. The parameterization of the angular distribution extends up to L = 3 and involves three angular distribution parameters B1, BS, B3.…”

“…On the theoretical side, both relativistic and nonrelativistic calculations were performed for a variety of cases using a more refined model [7,8]. On the experimental side, however, progress in this field had been hampered by the restriction to the limited spectrum and intensity obtained from the x-ray sources used (cf.…”

Nondipole effects in soft X-ray photoemission

“…1). Several parameterizations, all equivalent, are available in the literature (Amusia et al, 1974Scofield, 1989;Pratt, 1989, 1990;Cooper, , 1992Cooper, , 1993. Due to its ease of comparison with existing experimental geometries, the parameterization of Cooper ( , 1992Cooper ( , 1993 has generally been adopted for the photoelectron differential cross section in the first-order nondipole approximation for 100% linearly polarized light:…”

“…This pioneering work was followed in the ensuing decades by extensive theoretical efforts (Tseng et al, 1978;Cooper and Manson, 1969;Peshkin, 1970Peshkin, , 1996Pratt et al, 1973a, b;Amusia et al, 1974Amusia et al, , 1986aAmusia et al, , b, 1999Amusia et al, , 2001aAmusia and Cherepkov, 1975;Ron et al, 1977Ron et al, , 1994Kim et al, 1980;Wang et al, 1982;Pratt, 1989, 1990;Scofield, 1989Scofield, , 1990Cooper, , 1992Cooper, , 1993Seaton, 1995;Kronberg and Miraglia, 1995;Pratt and LaJohn, 1995;Kabachnik and Sazhina, 1996a, b;LaJohn and Pratt, 1998;Manson, 1999, 2001;Johnson et al, 1999;Derevianko et al, 1999;Connerade et al, 2000;Nefedov and Nefedova, 2000a, b;Nefedov et al, 2000a, b;Johnson and Cheng, 2001;Dolmatov et al, , 2003Cherepkov and Semenov, 2001a, b;Trzhaskovskaya et al, 2001;Grum-Grzhimailo, 2001, 2003.…”
