236PA c The decay scheme of 1984Mi02 supersedes the scheme of 1973Or06
236PA2c because of the observation of more complete |g rays in cascades.
236PA c 1984Mi02: {+236}Th decay was assigned based on the correlation of
236PA2c {+236}Pa daughter decay in equilibrium from {+236}Th sources produced
236PA3c by {+238}U(p,3p) followed by chemical and mass separation
236PA c 1973Or06: {+236}Th sources produced by {+238}U(p,3p)
236PA c Other: 1973Ka10.
236PA c x-ray: I|g(Pa K| x ray)/I|g(642|g)=0.32 {I8} from an equilibrium
236PA2c source gives I|g(Pa K| x ray)=(0.32 {I8}) x 0.37 {I2} x 100=12% {I4}
236PA3c (per 100 |b{+-} decays of {+236}Pa) (1973Or06).
236PA cG E,RI$From 1984Mi02, unless otherwise noted. Absolute intensity from
236PA2cG 1984Mi02 relative to I|g(642|g) in {+236}Pa at equilibrium, corrected
236PA3cG by parent/daughter ratio of 0.76 based on their lifetimes.
236PA cG M$From I(K| x ray)/I|g suggesting that most of the intense |g rays
236PA2cG with E|g>112.6 keV (the K-shell binding energy in Pa) should be M1
236PA3cG (1984Mi02).
236PA cL E$From least square fit to E|g's by evaluator.
236PA cL J$From adopted levels.

236PA cN NR$1984Mi02 provide absolute intensities noting "The gamma-ray
236PA2cN intensities of the parent 37-min {+236}Th were also put on an
236PA3cN absolute basis through measurements in sources in which parent
236PA4cN and daughter were in equilibrium; proper account was taken of
236PA5cN the parent/daughter ratio (0.76)."
