214FR c  2017Su18: {+218}Ac was the decay product of {+222}Pa produced in
214FR2c  reactions {+187}Re({+40}Ar,|a3n) with pulsed beams at 188 MeV;
214FR3c  evaporation residues (ER) were separated in-flight by the recoil
214FR4c  separator SHANS and implanted to a double-sided strip Si detector
214FR5c  (DSSSD). |a decay of {+218}Ac was studied by
214FR6c  ER-(|a{-1})-(|a{-2})-(|a{-3}) chains using time and position
214FR7c  correlations.
214FR c  2019Mi08: {+218}Ac was the decay product of {+222}Pa produced in
214FR2c  reactions {+181}Ta({+48}Ca,3n){+226}Np or
214FR3c  {+181}Ta({+48}Ca,3n){+222}Pa with pulsed beams at 212, 217 and 226
214FR4c  MeV; evaporation residues (ER) were separated in-flight by the
214FR5c  velocity filter SHIP and investigated using the COMPASS decay
214FR6c  spectroscopy station with digital electronics at the focal plane. |a
214FR7c  decay of {+218}Ac was studied by ER-(|a{-1})-(|a{-2})-(|a{-3}) chains
214FR8c  using time and position correlations.
