187W H TYP=FUL$AUT=Balraj Singh$CIT=ENSDF$CUT=31-Mar-2022$
187W c 2022Mu10: {+187}Ta was produced at the KEK Isotope Separation System
187W 2c (KISS) of RIBF-RIKEN facility in multinucleon transfer (MNT) reaction
187W 3c W({+136}Xe,X),E=7.2 MeV/nucleon at the RIKEN Ring Cyclotron.
187W 4c Target-like fragments were thermalized, with element-selectively
187W 5c reionized by using a laser resonance ionization method, followed by
187W 6c A/Q selection using a dipole magnet with a high mass resolving power.
187W 7c Measured E|g, I|g, |b{+-}, |b{+-}|g-coin, half-life of {+187}Ta decay.
187W cG E,RI$From Table I in 2022Mu10. Note that E|g values listed in
187W 2cG authors' level-scheme Fig. 3 seem to be either from level-energy
187W 3cG differences, or rounded values from {+187}W Adopted Gammas, thus,
187W 4cG are slightly different from those in authors' Table I
