Discovery of the calcium, indium, tin, and platinum isotopes

Abstract

a b s t r a c tCurrently, twenty-four calcium, thirty-eight indium, thirty-eight tin, and thirty-nine platinum isotopes have been observed and the discovery of these isotopes is discussed here. For each isotope a brief synopsis of the first refereed publication, including the production and identification method, is presented.

Current status and future potential of nuclide discoveries

“…Although not impossible it is unlikely that further nuclides will exist for which characteristic resonance parameters can be measured. 63 Se not measured 35 68 Br not measured, but 69 Br unbound 36 68 Kr not measured 37 72 Rb not measured, but 73 Rb unbound 38 72 Sr not measured 39 75 Y not measured 40 77 Zr not measured 41 81 Nb Z. Janas 1999 GANIL [150] 42 82 Mo not measured 43 85 Tc Z. Janas 1999 GANIL [150] For neutron rich nuclei characteristic properties of at least two isotopes beyond the neutron dripline have been identified for the lightest elements, hydrogen, helium and lithium. Neutron rich nuclides between beryllium and magnesium which have been shown or expected to be unbound but have not been observed are listed in Table 5.…”

“…Table 4 lists the first isotope of elements between aluminum and technetium which has been shown to be unbound but which has not been identified yet or the first isotope for which nothing is known, so that in principle it still could be bound or could have a finite lifetime. With maybe the exception of scandium, bromine and rubidium where resonances have been already measured for 38 Sc [141], 69 Br [142] and 73 Rb [143], resonance parameters for at least one isotope of these elements should be in reach in the near future.…”

“…In addition to these 66 nuclides another six new nuclides ( 64 Ti, 67 V, 69 Cr, 72 Mn, 70 Cr and 75 Fe) were reported in a contribution to a conference proceeding [164].…”
