Threshold anomalies in low-nucleon systems

I. Avrasya Nükleer Bilimler ve Uygulamaları Konferansı : 23-27 Ekim 2000. İzmir, Türkiye. Nature and mechanisms of threshold states in nuclear reactions are discussed, spectroscopy information that can be obtained with these phenomena studies is analyzed. The following situations in low-nucleon systems are considered: A = 10,7Li(t,p)9Li reaction near the threshold 7Li(t,n)9Be*(T=3/2), 7Li(3He,p)9Be reaction near the threshold 7Li(3He,n)9B(T=3/2); A=14, n B(t,p)13B reaction near the threshold n B(t,n)13C* (T=3/2), 10B e(α,p)13B reaction near the threshold 10B e(α,n)13C*(T=3/2). The results are reported o f quantum characteristics evaluation of 10Li neutron-unstable nucleus obtained trough the analysis o f threshold anomalies in 7Li(t,p)9Li reaction, and comparison with calculated and experimental reference data is shown. Performance of new experimental researches within this area is also discussed
