Capture of 10?100 keV Neutrons in Isotopes of Titanium

Abstract

Gamma ray spectra are presented as functions of neutron energy for capture of 10?100 keV neutrons in natural titanium. The spectra are dominated by transitions to the first, third, and fifth excited states of 49Ti which show strong fluctuations with neutron energy. The nature of these fluctuations and their relation to the nature of the capture process is discussed. A small but measurable strength in the transition to the 7/2? ground state of 49Ti has been observed and this is interpreted as evidence for the existence of a d-wave resonance in the reaction 48Ti(n, ?)49Ti at 39 keV. Transitions at 8260 and 8380 keV are assigned to capture in 47Ti.
