Implementation of TTIK method and time of flight for resonance reaction studies at heavy ion accelerator DC-60

α-cluster resonances in light nuclei

“…This signal together with a "start" signal from RF of the cyclotron was used for the Time-of-Flight measurements. The combined E-TF measurements enable us to minimize the background and to separate elastic and inelastic scattering [7]. The TTIK approach provides for a continuous excitation function as a result of the slowing down of the beam.…”

Structure of Ne20 states in resonance O16+α elastic scattering

“…The experimental setup was similar to that used before [19], and more details can be found in Refs. [17,19]. The main errors in the present experimental approach are related to the uncertainties of the beam energy loss in the gas.…”

“…The experiment was performed at the DC-60 cyclotron (Astana) [17] which can accelerate heavy ions up to 1.9 MeV/nucleon of energy. While the TTIK method can't compete with a classical approach in terms of energy resolution, the possibility of observing excitation functions at and close to 180 degrees, where the resonance scattering dominates over the potential scattering, enables one to obtain more reliable information on the broad states.…”

“…This signal together with a "start" signal from RF of the cyclotron was used for the Time-of-Flight (TF) measurements. This E-T (EnergyTime) combination is used for particle identification in the TTIK approach [16][17][18]. Of course, only α particles should be detected as a result of the interaction of 16 O with helium at the chosen conditions.…”

“…From an experimental perspective, the aim of this work is to obtain new information on the structure of 20 like other experimentalists, we used the Thick Target Inverse Kinematics method (TTIK) (see [15][16][17][18][19] and references therein) to study the excitation functions for the 16 O(α,α) 16 O elastic scattering in the 20 Ne excitation region of 5.5 − 9.6 MeV and in a broad angular interval. On the theoretical side, we also used multi configuration shell model calculations to understand the limits of this approach in the description of the cluster states.…”
