Use of styrene monomer-modified polyester in the fabrication of tissue-equivalent phantoms
Autor: H. Gaballa, E. Schutz, R.D. Zwicker
Publikováno v: Medical Dosimetry. 19:175-178
Tissue equivalent materials are often required both for routine quality control and for specialized studies in radiological physics. This work describes techniques and materials for casting of dosimetry devices from a widely available commercial resi

Numerical study of pseudowavefunctions for alkali atoms
Autor: R.D. Zwicker
Publikováno v: Journal of Physics and Chemistry of Solids. 38:481-485
Smooth pseudowavefunctions based on known valence and core functions are calculated and displayed for atomic Li, Na and K. These are used to examine some of the approximations employed in pseudopotential calculations; in particular, that of replacing

Planning of Ir-192 seed implants for boost irradiation to the breast
Autor: Rupert Schmidt-Ullrich, B. Schiller, R.D. Zwicker
Publikováno v: International Journal of Radiation Oncology*Biology*Physics. 11:2163-2170
The conservative management of early stage breast cancer with tumor excision and irradiation of the breast is becoming increasingly accepted as an alternative to modified radical mastectomy. The radiotherapy typically consists of 45 to 50 Gy delivere

Pressure shifts of F-center hyperfine interaction parameters in alkali chlorides
Autor: R.D. Zwicker
Publikováno v: Solid State Communications. 24:iii
We report here calculated values of the pressure shift in the shell I hyperfine interaction constants for F -centers in KCl, NaCl and LiCl. The calculation is based on a modified version of the pseudopotential approach of Bartram et al . with electro
