(Pointed out by J. Yarba et D. Wright) Version 4.3 (November 2015) Dennis Wright ------------------------------------------ - Laurent Desorgher produced new files with February 2015 input data from ENSDF and nuclear wallet cards. Q values were computed with QCalc. Data overlapping with those in PhotonEvaporation3.2 and G4ENDSFSTATE are intended to be consistent. - Luis Sarmiento's proton, neutron emission and spontaneuos fission lines, files added - for detailed comments from Laurent on buidling the database for this version, see file README_build Version 4.2 (November 2014) Dennis Wright ------------------------------------------ - added Laurent's new files which fill in missing alpha levels and remove spurious ones: z53.a113 z54.a111 z60.a144 z66.a156, a158, a160, a161, a162 z69.a155 z71.a155, a159 z72.a159, a164, a174 z73.a158, a163, a164 z74.a163, a164, a167, a168 z75.a163, a165, a167, a168, a169 z76.a163, a164, a168, a172, a186 z77.a167, a168, a170 z78.a172, a184, a185, a186, a192, a194, a195, a196, a198 z79.a179, a180, a187 z80.a172, a178, a186 z81.a181 z82.a182, a184, a192, a194 z83.a184, a185 z84.a186 z85.a193, a194 z86.a214, z86.a216 z87.a199, a223 z88.a202, a216, a218 z90.a212, z90.a214, a220 z91.a214, a220 z92.a218, a222, a224 z93.a227, a228, a230, a231, a233, a236 z94.a228, a229, a230, a233 z95.a234, a235, a236 z96.a233, a237 z98.a237, a239, a241 z99.a244 - added Laurent's new files which fill in missing beta- levels z19.a53 z25.a62 z27.a73 z35.a78 z39.a102 z41.a104 z46.a115 z47.a118 z67.a168 z75.a187 z82.a115 z83.a212 z99.a254 - added Laurent's updated beta+ files z38.a78 z43.a94 z47.a102 z48.a96 z49.a104 z55.a116, a119 z59.a134 z60.a133, a135 z61.a136 z66.a145 z67.a151, a153 z69.a154, a160 z72.a160 z73.a156 z77.a172 z79.a178, a189, a192 z80.a189, a191 z81.a184 z82.a189, a199 z83.a197, a200 z84.a201 z95.a235 z99.a242 z100.a253 - files z55.a136 (IT) and z58.a129 (beta) had nan in place of intensity value - replaced with value of 1.00 Version 4.1 (February 2014) Dennis Wright ------------------------------------------ - contains Laurent Desorgher's corrections for X,Y,Z,W and A levels. For consistency it should be used only with PhotonEvaporation3.1 or later - D.H. Wright: added observationally stable (very long lifetime) ground states to 20 nuclides. 4 are thought to decay by alpha emission, 6 by double beta+ decay and 10 by double beta- decay. G4RadioactiveDecay.cc now recognizes double beta- and double beta+ decays, but currently does nothing when they occur. Version 4.0 (September 2013) ---------------------------- - update to ENSDF 2012 by Laurent Desorgher Version 3.7 (7 June 2013) ------------------------- - 24 files were found in which entries for a given nuclear level and lifetime were entered twice. Duplicate entries were removed from these files: z37.a98, z37.a99, z38.a98, z38.a99, z39.a98, z39.a99, z40.a98, z40.a99, z41.a98, z41.a99, z42.a99, z43.a98, z43.a99, z45.a114, z45.a98, z45.a99, z46.a98, z46.a99, z47.a98, z47.a99, z48.a98, z48.a99, z68.a147, z70.a151 Missing decay information for excited states added to: z47.a100, z60.a133 Correct half-life and add missing decay information to: z20.a48 Correct BetaMinus level 73.92 to 78.92 for z90.a234 Recompute from latest ENSDF: z41.a100 Remove BetaPlus and add Alpha decays: z100.a250 Version 3.6: ----------- - Added new files containing the forbidden Beta decay information for all nucleus known to have such decays in the ENSDF database.
