Charge-changing cross sections for ^42-51Ca and effect of charged-particle evaporation induced by neutron-removal reactions

NUCLEAR REACTIONS ¹²C(⁴²Ca, X), (⁴³Ca, X), (⁴⁴Ca, X), (⁴⁵Ca, X), (⁴⁶Ca, X), (⁴⁷Ca, X), (⁴⁸Ca, X), (⁴⁹Ca, X), (⁵⁰Ca, X), (⁵¹Ca, X), E=280 MeV/nucleon; measured reaction products; deduced charge-exchange σ. Comparison to Glauber-like model calculations. Observed significant decrease of charge-exchange cross-section with increase of point-proton radius and attributed this effect to attributed to the charged-particle evaporation induced by the neutron-removal reaction. Used the conclusions of the present work to re-analyze charge-exchange σ for Be, B, C, N, O, F, Si, Ti, Ca, Fe isotopes. BigRIPS fragment separator at RI Beam Factory (RIBF).
