Abstract

The probability of deuterons detected in Ge telescopes giving anomalously small pulse heights, due to their undergoing inelastic interactions and possibly elastic scattering, was measured from about 35 to 105 MeV. The loss factors, determined to 0.5% or better, increase from 3.1 to 12.2% in this region, and are consistent with a nearly energy-independent d + Ge total reaction cross section of about 2000 mb.

Measurement of the 6Li + natSi reaction cross section at 18 to 28 MeV with a magnetic spectrograph and position-sensitive Si detector
1992, Nuclear Inst. and Methods in Physics Research, A
The average reaction cross section σ_R for ⁶Li in ^natSi was determined from the ⁶Li energy spectrum in a two-dimensional position-sensitive Si detector in the focal plane of a magnetic spectrograph. The average σ_R for 18 to 28 MeV ⁶Li, 1490±80 mb, is compared with specific optical and strong absorption model calculations. Good agreement is obtained for certain models. This method for measuring σ_R may be particularly useful when only small particle fluxes (≤100/s) are available; e.g., for radioactive nuclear beams.
Total nuclear reaction probabilities and average cross sections for 16 to 23 MeV 6Li in silicon
1990, Nuclear Physics, Section A
Total reaction probabilities for 16 to 23 MeV ⁶Li with Si, for reactions with Q outside the range −3.5 to +1.2 MeV, were measured by injecting ⁶Li ions into silicon detectors. Partial cross sections for direct three-body ⁶Li breakup (with or without a spectator) were determined by standard coincidence methods. A novel αd coincidence technique was used to measure the cross section (24 ± 2 mb) for inelastic scattering to the ⁶Li(2.184 MeV) level. These combined measurements give an average reaction cross section of 1200 ± 320 mb in this energy range, which is in agreement with optical model predictions. Reaction losses of ⁶Li in silicon detectors are found to be less than 0.05% for incident energies below 23 MeV.
Nuclear reactions in silicon and germanium detectors and peak intensity losses for helions
1987, Nuclear Inst. and Methods in Physics Research, A
Using the optical model, with parameters that fit the elastic scattering data, the reaction cross sections of helions interacting with silicon and germanium have been obtained. With the range-energy relation and the reaction cross section as inputs, the peak intensity losses for helions in solid state detectors have been determined. It is found that the corrections to detection efficiency due to the reaction losses can be as high as 10 to 15% for 300 MeV helions.
