Az előadóról: 


Professor Susanta Lahiri, a co-creator of element Z=117 Tennessine, received 
the Hevesy Medal Award in 2015 for his outstanding contributions to heavy ion 
induced radioisotope production, tracer packet technique, converter targets 
and green chemistry. 




Kivonat: 



Converter targets (CT) are high Z target materials, like liquid Hg, Pb-Bi 
eutectic 1 (LBE), Pb-Li eutectic (LLE) and also the high Z refractory 2 
elements like Ta or W. The converter targets can be large source of 
clinically important non-conventional radioisotopes. To this end, for the 
first time we have identified the residual nucleus arising from the 
interaction of 1.4 GeV proton beam with LBE targets. Attempt has been made to 
understand the underlying reaction mechanism by analysing the residual 
nucleus. Radiochemical methods to isolate the no-carrier-added radionuclides 
have been developed. 



1 An eutectic mixture is a homogeneous mixture that has a melting point lower 
than those of the constituents. 

2 In planetary science, any material that has a relatively high equilibrium 
condensation temperature is called refractory.
