![]() The spectroscopic amplitudes are compared with those given by simple weak-coupling model predictions there is considerable disagreement, probably because too few configurations were used in the theoretical calculations.Alfred Adler was born in 1870, the second of six children in a family who lived in the suburbs of Vienna. The internal consistency of this set was verified by using sum rules. A set of spectroscopic amplitudes was then found, for both the single-particle and the particle-core components of the parent states, by comparing the best-fit resonance parameters with those given by model calculations. The data for inelastic scattering to the first excited state (2/sup +/, 0.803 MeV) more » were described using a distorted-wave Born approximation background and the same isobaric analog resonances good fits to the data were obtained by varying only the inelastic partial width amplitudes. Excellent fits to the elastic scattering data were obtained using a parametrized background and the isobaric analog resonances of 35 states in /sup 207/Pb (the ''parent states'') with E/sub x/ = 2.3-5.7 MeV spin-parity assignments and resonance parameters were determined for all of these isobaric analog resonances. « lessĮxcitation functions have been measured for the elastic and inelastic scattering of polarized protons from /sup 206/Pb at theta/sub lab/ = 120/sup 0/, 135/sup 0/, 150/sup 0/, and 165/sup 0/ in the energy range E/sub p/ = 14.25-18.00 MeV. A cooled detector system, capable of identifying protons responsible for K-shell ionization in zero-impact-parameter collisions, was developed to measure coincidences between Ba x-rays and protons scattered to an angle of 172 eV. The effects of nuclear reactions on inner-shell ionization of atoms were studied with protons incident upon isotopically enriched barium targets. ![]() Numerical calculations of the ionization probability show only a slight dip at the minimum in the p-C elastic cross section, opposite in sign and of much smaller magnitude than the reported variation. We also show how the more » amplitude for monopole excitation is augmented by the ''shake-off'' or ''sticking'' term found in the semiclassical theory of Ciocchetti and Molinari, and display the formal correspondence between the semiclassical and quantum-mechanical theories. Assuming a potential description of the nuclear scattering, we make a completely quantum-mechanical calculation of the ionization probability in the distorted-wave Born approximation and show that angular momentum effects do not account for these results. Since the resonance was so wide that time-delay effects on K-shell ionization should be very small, it was hypothesized that this effect was due to the exchange of angular momentum between the projectile motion and electron. Recently the measured proton-induced C K-shell ionization probability was found to vary significantly near the 0.461-MeV j = 1/2+ elastic resonance in /sup 12/C. The observed reaction times agree fairly well with the predictions of the classical nuclear reaction models used to describe deep inelastic scattering processes. From the data we infer a nuclear reaction time of approximately 1 x 10/sup -21/ s at Q = -100 MeV. rays, a strongly Q-dependent P/sub K/ is found, in qualitative agreement with theoretical predictions. After subtraction of the ionization induced by the internal conversion of. P/sub K/ was determined for Q values down to -190 MeV. The K-shell ionization probability P/sub K/ has been measured in the deep inelastic reactions U + U and U more » + Pb at a beam energy of 1785 MeV as a function of the total kinetic energy loss -Q. ![]() Therefore a measurement of P/sub K/ as a function of Q then yields. delta.T is monotonically related to the total kinetic energy loss (-Q) of the reaction products. In a deep inelastic nuclear reaction, the nuclear reaction time. delta.T, a phase change which affects the ionization probability P/sub K/ of the target- and projectile-like products is introduced between the incident and outgoing ionization amplitudes. If an atomic collision is accompanied by a deep inelastic nuclear reaction with a time delay.
